Review help

Well we started probability.

Number of favoured outcomes
_____________________
Number of possible outcomes

example: flipping a coin
you want to flip a heads
there is 2 possible outcomes and you only want 1 outcome.
so it would be a 50 50 chance or 1:2

if you have 2 dice, you multiply the number of sides(6 in total) on one die by 6 on the other
so 6x6=36 possible outcomes
you want a 2
there is only one possible outcome to get 2
so it would be 1:36 chance of rolling a 2.
This is theoretical probability.
Experimental probability is different.

Example: Even though rolling a 2 is 1:36 chance, you still can roll a 2 more than once in thirty six times.
to get the closest to theoretical pr4obability, you just keep on rolling the die.

Next we did algebra

A question I made up was:

A guy is trying to find a perimeter that is 128 feet for his flower bed. But because of his awquard(don't mind spelling) yard, the length has to be 6 feet more that 5 feet less than 2 times the side of the width. What are the length and width of his pretty flower bed?

To answer this go

l=
l=
w=
w=

Too bad exams are over! It was ""fun!""

kims fraction growing thingy

#1

Expressing fractions into lowest terms means, by dividing the numerator and enominato by the same number.
#2
Improper fractions and mixed fractions are the same because they still reprsent the same fraction. eg. 9/5=1 4/5.

#3
Do this later if its okay with you! :)

#4
Ryley was making a cake. He needed 3/4 of a cup of milk, 2/3 of a cup of butter, and needed 1/4 of a cup of baking soda. How many ingriedents all together does he need.

#5
I'll do that later!

#6
Find some later!:)

Jenny's Fraction Growing Post Part II

1) I think this is how you do it..

2) You multiply the two numerators and the two denominators...
( You can also cross reduce to make it more simple)
( Dont forget to change it into a mixed number and put it into lowest terms)

3) Multiplying Fractions
This site is a good site that explains how to multiply fractions. It has simple rules at first then it shows you step by step. It has three different games that help you
practice multiplying fractions. It also shows you how you can cross reduce. .

4) When you divide fractions you use a reciprical? Or the additive inverse? You flip the second fraction. Then you just multiplty it like you would when you multiply fractions.

5) Dividing Fractions
This website is good for learning how to divide fractions. It gives you the rules and it shows you how to do it with an example. It also has some games that help you practice.

6) In room 41 I chose Tyler's Post because I could read it clearly.
In room 17 I chose Katho's Post because I liked the pictures.
In room 16 I chose Annalyn's Post because she explained everything really good.
In room 73 i chose Ingrid's Post because the animations helped me understand it better.

7) If i was stuck driving behind some crazy driver
that only drove at an average speed of 90 km, for 1 1/4 hours, how far would I go?!?

I answered Katho's question..

1. The picture on the left is 5/6 The picture on the right
is 54/30 also 9/5
Like my flags??






2. 1x1=1 1 over 30 okay
5x6=30









3. This site about Multiplying Fractions is from Enchanted Learning. THis site as everything about multiplying and dividing if you click on the links. THis is a good site because you can also use it as learn about other subjects.

4. 1x4=4 =1
4x3=12=3


5. THis is practically the same Site because enchanted learning has everything about learning
6. I nominate Deannia's because hers is the only other one than mine that I see
I nominate Katho I think because that also is the only one I can see
I nominate Me because I only see three and I be one of them HArbuck can I skip the rest of the nominations because no one is going to post tonight so I don't think I will remember to come back and nominate other people.

7.Someone has a lemon murang(don't mind the spelling) pie loded with cherries is cut into 8ths.
You get half of the eight pieces. You decide to share 2/3 of your share. How much pie does each have?

Deannia's Second Fraction Growing Post

1.)OK! Well i know what how do it because you just make pictures. Like for 5/6 you would have it drawn out and 5 covered (cause thats what you have ). Then for 9/5 thats would be improper so you would have to change it to

so that would be 1and 4/5.



2.) Here are some things you should remember when you multiply.
-x numerator x denominator
-mixed numbers are made into improper fractions
-whole numbers are written as whole/1
-look for cross reduction
-all improper answers should be changed into mixed numbers

Numerical Example
2/3x1/3=2/9 all you do is times the numerator by the other numerator and then do the same thing for the denominators

Well i did a picture example at its at the top of the page because i dont know how to move down here and when i try and do something it does nothing.

3.) This website talks about how to multiply do fractions. This site also shows anything else that you would need to know about fractions.This is the website that i chose but i do not get how you link it so yea http://http://www.coolmath4kids.com/fractions/index.html.

4.) Here are some things that you should know when dividing fractions.
-Yours is not to reason why just invert and multiply.

Numerical Example
8 divided by 2=4 Eight is how much you have, 2 is how many groups (size), and 4 is the new group.

My picture example is at the top of the page with the other one i have know clue how to move them done here. Anybody that does can you please tell me.

5.)This website tells you how to divide fractions. It also tells you other things that you need to know about fractions and such. Here is the websites http://www.coolmath4kids.com/fractions/index.html im dint know how to create a link so i just gave the website.

6.) Ok, well i nominate (if thats how you spell it) I think its tylers (8-41)cause it has good pictures and its the only one i see so yea i also nominate umm michael s.(8-17) cause he had good pictures and lots of info,next is ingrid (8-73) cause she had great pictures and very good information, and the last one is annalyn cause she had good pictures and good information. Sorry people i dont know how to make a link so your just going to have too look at them yourselves.

7.) A chocolate bar has 8 equal pieces. You split into into 1/2. How much do you have left?? This is an easy one so you people should be able to get it. Ok well you dont see a picture cause its at the top of the page..I answered tylers (cause i dont see anyone elses) question i just dont know how to create a link to it.

Great well im done, good job for me!!!

Junnel's Fraction Growing Post

to make a fraction into the lowest term..you have to use a number that can divide the numerator and denomenator...

mixed numbers and improper fractions are mixed fractions because when you divide the numerator with the denominator..

3. press on "practice game" . it helps you on mixed fractions
4. a) if there are 3 apples that your admirer gave you and you ate 1 and 1/2 of the apples how many apples would you still have??

Jenny's Fraction Growing Post..

1) Expressing fractions in lowest terms is when you reduce the fraction to the simplest terms possible(by dividing both the numerator and denominator by the same number)..




2) An improper fraction is where the numerator is larger that the denominator, so its like there is one equal whole plus some parts..
A mixed number is pretty much the same thing except the whole is not combined with the actual 'fraction part'..


3)a website that explains how to simplify fractions to the lowest terms.
It also has a little 'activity' you can do to help you understand how to reduce fractions..

4) a) If you have 3/4 of pepperoni pizza and 4/5 of cheese pizza, how much pizza do you have??

b) Jenny has 10 1/2 doughnuts. She gives some guy 5 1/2 of them. How many doughnuts does she have left??

5) Stephanie 8-73, Jeff 8-17, Dhonna 8-16

6)
They all have an 'activity' at the bottom to help you understand how to subtract fractions...

Subtracting fractions with same denonimators
Subtracting fractions with diff. denominators
Subtracting mixed fractions

sachelles growing fraction post

1.
Expressing fractions in lowest terms is reducing the fraction to the lowest it can go.

4/8 divided by 2(both numbers) is 2/4 now you divided by 2 is 1/2. Now that is the lowest it can go because you can't divide any more.












2.
Improper and mixed numbers are the same because they can equal each other

So you have 1 1/3. You take the denominator and multiply it by the whole number. The you add the number you now have to the numerator. So 3 multiplied by 1 is 3 and 3 add 1 is 4 so you now have 4/3. You keep the denominator the same. Now to make the improper fraction a mixed number you see how many 3's are in 4. So there are 1 then how many is left over 1. So now you have your mixed number. 1 1/3.


3.Here is my site for equivalent fractions http://www.aaamath.com/fra42a-idequivfract.html. This site explains how to do equivalent fractions and there is some games so you can practice doing them.

4. You have 2/4 of a pizza and your friend gives you 2/3 more. How much pizza do you have now?

b) You have 2 3/5 of a chocolate bar but you give your friend 1 1/2 of it. How much of the chocolate bar do you have left?

6. Here is a site for adding and subtracting fractions http://www.aaamath.com/fra.html. This site can also show you a bunch of different fractions.

Second Growing Fraction Post

1. Im not really sure what to do.













2. When you multiply fractions you get a new fraction.
If you don't understand my writing because it's not really descriptive look at my numbers.oh yeah.

1/2 x 2/3=
the numerators multiply with each other.
1x2=2
the denominators multiply with each other
2x3=6
so the answer is 2/6......... for mixed numbers, make the mixed number into an improper fraction before multiplying.

3.This is my website for multiplying fractions. This website will show you how to multiply fractions and other stuff on fractions.

4.When you divide fractions you use reciprocal and then multiply.

1/5divided by 2/3
You change 2/3 to it's reciprocal and once the reciprocal is changed you multiply
1/5 x 3/2
1x3=3
5x2=10
3/10

5.Here is a site for dividing fractions.
You can learn how to divide fractions here. You can also learn how to do other stuff with fractions.

7. You have 2/3 of a chocolate bar and someone gives you double that. How much do you have now?

Soriano's Fraction Growing Post


PART 1
May1&2.06

Ouestion1.

I think... Also, u have to divide the numerator and the denominator by the same number, and 1/2 is the smallest term, because you cannot devide any lower..

Question2.
Improper fractions and mixed numbers are the same because, to make a mixed fraction u need an improper one.
Eg. 9/4 <- there are two more groups of 4/4 so the answer will turn out as 2 1/4 because there is an extra 1/4. To turn a mixed fraction to an improper one, you need to multiply the denominator with the whole number, then add the numerator. Eg. 2 1/4 <- 4x2=8+1=9 so the answer is 9/4.

Question3. http://www.themathpage.com/ARITH/equivalent-fractions.htmnt-fractions.htm
This site shows how to make, equivalent fractions, it also tells you how to make them into lowest terms. The easiest way to.

Question4.
A. Harry and Horhay go and buy candy. Harry takes 3/4 of candy from his bag, and Horhay takes 1/2 of candy from her bag. How much candy have they eaten altogether?

B. Earl and Horhay went to the store to buy clothes. Earl buys 20 3/4 dollars in clothes, and Horhay buys 19 9/10 dollars worth of clothes. How much more has Earl spent on clothes than Horhay.

Question5.
Ashley Amantes's, Yvanne Dandan's and Annalyn Aniciete's

Question6.
HERE http://www.themathpage.com/ARITH/add-fractions-subtract-fractions-1.htm
This page shows how to add and subtract fractions, and which common denominator is better to use. Like instead of 1/3 = 30/90, 5/10 = 45/90

PART 2
May 14.06
Question1.
BEWARE! - GUESSING BELOW!

Question2.


Question3.
I dont know if this is really an easy site to help you learn multiplying fractions but i guess its better then nothing. This site wil show you the steps into multiplying fractions. It also has helpful questions that can help you.

Question4.


Question5.
I also dont think this is an easy site to learn dividing fractions. It does show you what the steps are to dividing. Being the same website i used=D i think theres example questions that you can do=D

Question6.
From 8-41=D I nominate Dion - he had a good blog like hyper active stuff, he had nice pics and gifs lol. GOOD JOB DION!
From 8-16 =D I nominate Dhona - she had a nice blog, easy explinations and everything. BERRY GOOD Dhona!
From 8-17=D I nominate Rebecca - she had a nice and easy way to learn the stuff. Good Work BECCA!
From 8-73=D I nominate Aldrin - his blog seems to be the favoured and i dont disagree, his pictures come right at you like 3-D. Nice Work Aldrin!

Question7.
WARNING -- UNDER EXAJURATION AHEAD - dont mind the spelling

If there are lets see... 1..2..3..4..5.. 26 Naruto Uzumaki's (including himself) altogether, and The original puts them into groups of 7. How many groups are there?

I had done Helen's Question - I had posted the answer to her comments aswell=D

it's mothers day!! and you decide to buy your mom flowers. So you go to the flower store and to your surprise you find out there is a mother's day sale! Daisies and lilies for 1 dollar each without tax. You pick out 5 lilies and 3 1/2 daisies. You brought a 10 dollar bill with you how much will change will you get?

So 5+3 1/2 =8 1/2
Its like saying $8.50
So $10.00 - $8.50 = $1.50 or 1 1/2 of the change is yours... i guess=P

FOR NOW

1.

2. Mixed fractions and improper fratctions are the same because they basically mean the same thing. Say you have an improper fraction of 10/7 you can also write it as a mixed fraction.

10/7 = 1 3/7

3. http://www.visualfractions.com/LowestCircle.html it explains how fractions are in lowest terms.. yaadaa yaadaa yaadaa... with some circle.

4. a) If a basket of apples weighs 3/4 lb. and a basket of pears weighs 2/3 lb. How much do the baskets weigh together?

b) If you have 3 1/2 pizzas and you and your friends eat 2 1/4 how much pizza is left?

5. suuuuuuuuuuurrrrrrreeeeeeee

6.http://www.visualfractions.com/ its basically the same website as # 3 but this time its not on a particular page its the whole website! And its also talks about dividing and multiplying fractions if your interested.

Part 2



3. If your having trouble understanding how to multiply fractions click here.

This site seems simple enough to understand. It even has a game (*cough*) for you.




5. If your having trouble understanding dividing fractions click here.

It seems really easy to understand. It shows you examples and stuff. It has a glance, in depth, examples and workout pages for you to practice.

6. From 8-41 I nominate Dion cuz of his graphics.
From 8-16 I nominate Helen because of her use of pictures and she seems to knoe what she's talking about.

What's a Fraction Growing Post??






1. 2/4=1/2 because the numerator and denominator both have a common factor- 2














2. they both reprisent a number/fraction larger than one
3. + 6. This is the site which I choose because it not only provides a fraction site, it also provides many of the things we learned this year, so it could be used to review for the exam as well.

4. a)I have a three piece chocolate bar and a four piece cake. I ate 1 piece of chocolate and 1 piece of cake. How much cake and chocolate do I have all together?

b) Terrible Ted took 3 and two thirds of the toast. Ted ate two and two thirds. How much did Terrible Ted have left?

5. I will...
Ok... I posted on Josh and Jenny's in 8-41 and Ingrid's in 8-73

Part 2.

If Dion can make gifs, so can I muahahahahaha...but not quite yet...
1. Later...ok it's later now. So, there's 5/6 eh... Well, first is to make it a whole, which would be 6/6. THis is the same as 5/5. Now you only need to add the remaining 4/5 to the whole and Voila!!! You have 9/5. Hooray! You can also simply use a common denominator which in this case is 30.











2. Numerators get multiplied and denominators get multiplied












3.+ 5.I choose the same site I used earlier because it has all of the stuff we need!

4. "Yours is not to reason why,
Just invert and multiply!"-C. Harbeck, Math Class 2006
So, you invert the second of two fractions involved with the equation and multiply.









6. I nominate Ingrid of 8-73 because she used really good pics and good questions.
I nominate Katho of 8-17 because it has good pics.
I nominate Dhona of 8-16 because she used nice pictures as well and good examples
I nominate Dion cause of his gifs

7. A jelly donut is 3 1/2 inches in area. It is 3/4 jelly. How much jelly is in the jelly donut?
