Kale's Growing Fraction Post

Part 1

http://www.enchantedlearning.com/math/fractions/ This is a good site that covers up most about fractions. Has about a page describing them.

If billy has 3/4 of an apple, and sue has 1/3 of an apple how many pices of an apple do they have?
this means 3/4+1/3
3x3=9
4x3=12

1x4=4
3x4=12 9+4=13. they have 13 out of 12 pieces.















The answer to your math question is 2/5 or two fifths. How many different questions can you make with 2/5 as an answer?Try adding, subtracting, mixed numbers, improper fractions etc. The sky is the limit. - There is an infinite amount of possibilties
blogger is acting weird


square: 5/6 to 9/5
Make a whole=6/6 or 5/5, then add 4 fifths. = 9/5

#1. If u have a fraction like 5/15, its not in lowest terms because it can still be decreased, divide by 5 on the numerator and denomenator. Then you have 1/3 which is in lowest terms =
#2. Improper fractions and mixed numbers are the same, suppose you have a mixed number like 4 and 3/5ths, multiply the denomenator by the whole number than add the numerator. So its like 4x5=20+3=23/5ths as the mixed number. You can also go the other way by dividing. Divide 23 by 5 and it goes in 4 times so thats your whole number and the remainder is the numerator =
#3. www.visualfractions.com/renamelowest.html
This website offers instructions and practise in renaming fractions to lowest terms. All examples are pictured in number lines =
#4. Chris Harbeck has 2\3rds of...a bug(lol) and his friend...Mr.Ramsoomair has 3\4ths of a coconut, Harbeck suggests that they should put the 2 together and see what happens. How much do they have together? =p

#5.Gonna do that at end :)

#6.Click here

This website tells you how to add or subtract fractions in a complete course of arithmetic.

#7.Done.

-----------------------------------------------------------------------------

part 2!

1.so the shape of square has side lengths of 5 and we need 2 show wat the fraction 9\5 is by using the square? hmm seems hard..but it isnt. the whole is 6\6, then its 5\5 then add 4]5 and its 9\5 :p

2. NUMERATORS AND DENOMINATORS GET DIVIDED...

3. L1nk - an interactive math source of how to multiply fractions.

4.as a guy by the name of charbeck once said, yours is not the reason why, oh no, just invert and multiply...i added the oh no :) lol

5.in this website they discuss dividing fractions...the dividing rules...they also have multiplying

6.in our class..dion or matthew, didnt decide who though but either one of those 2 should be in the hall of fame, they finish posts on time and they are pretty good :p aldrin from room 73 because its all good. katho and dhono are also good bloggers.

7. i drank some of my gatorade it is now 4\5th from full, i drink 2\5th more then my friend puts soem of his gatorade and tis 4\5th to the 2\5th, how much gatorade do i have-lol its kinda confusing

Deannia's Growing Post

1.) When expressing frations in lowest terms you have to make the smallest piece that you can.
6/12 divided by 6/6=1/2 or 6/12 are 1/2
are equivalent but 1/2 is the smallest piece possible. Lowest terms may also be called simplifying or reducing.

2.) A mixed number is a whole number and a fration.
l1/2
A improper fraction is when the numerator has more parts than the denomenator.
5/4 thats improper
These are similar because both are still not a normal fraction. (i guessed here)

3.)http://www.coolmath4kids.com/fractions/index.html
This site has anything you need to know about fractions. It tells you everything you need to know and it explains how to do them. This site can also be used for number 6, cause it tells you how to add and subtract fractions.



4.) a.) Bob was making a cake for his wife. He needed 3/4 cups of milk, 2/3 of eggs and 3/5 of flour. How much ingredenints did he have in total.
b.) Joe has ate 1 3/5 pieces of chocolate cake, then he ate 1 1/5 of ice cream cake. How much more of chocolate cake did Joe eat than he did ice cream cake.





5.) I went to 3 other people sites and left comments.

6.)http://www.coolmath4kids.com/fractions/index.html I used this sites in number 3 and number 6 because this site tells you everything you need to know about fractions.

Growing Post......Kirby


1) Say you have the fraction 4/8 . This fraction is not in lowest terms. To make it into the lowest term you have to find the common factor. The common factor for 4 and 8 is 2 or 4. So once you have found a common factor you have to divide both the numerator and the denominator by that number.































2) Improper and mixed factions are the same because if you have an improper fraction and turn it into a mixed number they are the same but expressed differently.






3) http://www.visualfractions.com/LowestCircle.html



This is a great site if you need help with making fractions in to their lowest term. It uses diagrams to help you understand it more.

4)

a)Georgina and Polly made a race track for their hamsters. Georginas hamster (Mac) only made it 3/4 of the way and Pollys hamster (Frank) made it 2/3 of the way. How far did the hamsters travel all together?

b) Polly and Molly bought the same cherry lipstick. by the end of the first week polly had 3/4 of it left, molly had 2/4 of it left. how much more lipsick did polly had then molly?

5) Yupper I posted a comment on Deannia's Sachelle's and in another room Racquels er however you spell her name.

6)http://www.jamit.com.au/htmlFolder/FRAC1007.html

This site is great for helping you add and subtract fractions. It tells you what to do when the denominators are and are not the same. Also on the site there is a game, it doesnt tell you how to do the fractions, there are just questions and you have to answer them.

7) Okie Dokie

Part 2

1. Okay i am really not sure what to do but i will do it the way i think i have to.

This is the fraction 9/5

There is one whole which is made of 5 pieces and there is a part of a whole 4/5 so one whole (5/9) plus part of a whole, 4/5, equals 9/5.

2. This is how you multiply fractions

3. This website shows you multiply fractions. It explains it well. There is also a couple games on it to. you could enter in fractions and it tells you how to multiply it.

4.This is how you divide fractions


























5. This website shows how you divide fractions. It shows you step by step on how to divide fractions. At the end you have to figure the questions out yourself.

6. ummm i dont know how to get to the other classes blogger. from our class i nominate jenny because she used lots of color and explained things well :P

7. FrankyBob planted some flowers. The next morning the plant grew about 1/8. in the next five days the plant tripled in size. how much did the plant grow all together?








Deannia's Question

8 divided by 1/2
= 8/1 times 2/1
= 16!!!!

Fraction Growing post



Question Number 1:

2/4 is the same as 1/2 becuase 2/2=1..4/2=2 there fore they are the same. you have to divide the numerator and the denominator by the same number.Therefore 1/2 is in lowest terms of 2/4 becuase thats as small as the pieces can get.

Question 2:

say you had 7/6 which is an improper fraction. The mixed fraction of 7/6's is 1 whole and 1/6. A mixed fraction equals a improper fraction.How? well... 1 whole multiplied by 6 plus 1 = 7/6 which equals the improper fraction. This how they are the same.

Question 3:

http://www.themathpage.com/ARITH/equivalent-fractions.htm

This site tells you what equvalent fractions are, and why they are and so on. This site is awsome also because they show you with pictures.

Tyler's Growing Fraction Post


1. As you can 2/4 is the same as 1/2 You can divide both the numerator and the denomenator by the same number that is higher than the #1
2 divided by 2 is 1 4 divided by 2 is 2 so 1/2


2. The one on the bottom represents a proper fraction. One and 1/2
The top represents an improper fraction. 3 halves
They are similar because to make a proper fraction. 3/2 only 2 goes into it once with one left over. 1 whole with one half.
To make it improper. 1 1/2 means a whole equals 2, 1x2=2 and then add 1 so 3/2.


3. http://www.enchantedlearning.com/math/fractions/reducing/ This site shows how to reduce a fraction to lowest terms. It has work sheets that can help figure out the strange world of Alphabets... I mean Fractions!!!!!

4. Since Dion use pie, I'm going to use something even better than it...... Apple PIE! So Tyler is sitting there with 74/3 of pies. While Tyler's Clone is sitting across the room with 2/4 of a pie.
So Tyler decides that His clone is hungry so he gives him half of what he has. How much will Tyler have and his clone after this exchange of Apple Pie?
(Hint) first you should change all the thirds and quarters to one common one.

4b. This time it will be in the form of Pumpkin Pie. So Tyler and his Clone are sitting in there same seats a week later. They both have 50 2/4 Pumpkin pies each. Tyler eats a quarter of his Pie. His Clone decides he's hungry and eats half of his pie. How much pie is left between them and how much did they eat?

5. http://www.enchantedlearning.com/math/fractions/ This is an overview of fractions. There are links to find different areas of Fractions including adding fractions. Also check out the rest of this site. There are millions of different things about science, social studies, and other subjects.

2) They mean the same thing or you could say they have the same amount
like: 3/2 is the same as 1 1/2
you can also divide example: 3 / 2 =1.5 so the mixed number would look like 1 1/2

3)I think this site would really help for people who don't understand site has practicing pages so you know what your doing


4.a)Felicity has 1/3 of an apple and Anna has 3/4 of an apple. How much of an apple does Felicity and Anna have all together?
b) If Linda ate 2 1/2 of a chocolate bar then gave her friend 1 1/2 of her chocolate bar how much chocolate does Linda have left?

Yay! First Fraction Growing Post!





1)Well expressing fractions in lowest terms simply means to get a fraction to its smallest form




2)well.........They are the same for they could be the same number just... written in a different... form

3) http://www.gomath.com/exercises/ReducingToLowestTerms.php
Like its got how to change into lowest terms and cool fraction type calculators for the job! =-) also has other subjects + calculators and places to test yourself

4a)Im going to use one of my favorite things in my problem... PIE! I have 7/4 of a pie (or several pies) and the person sitting next to me only has 2/3 of a pie. I lean over and say that we should combine or pies. He agrees. So how much pie do we have together?












4b)Im going to use pie again! I have...um ...lets see... 4 3/4 of a pie! Yay! So much pie! I got hungry and decided to eat 3 1/2 of my pie in one sitting! i probably couldn't do this but... this is an imagnary scenario! So how much pie would I have left?

No pie was harmed in the making of these questions




5) I answered Kale's questions (8-41), Aldrin's questions (8-73) and Mike L.'s questions (8-73)

6) http://www.math.com/school/subject1/lessons/S1U4L3GL.html
Crazy website! Its got the whole scoop on pretty much everything you want to know about fractions! It explains how to do like everything with cool pictures too! =-)

Extra)I left comments on the posts i answered questions too!








Please dont copy my idea! Hope you like it!
-----------------------------------------------------------------------------------
Part 2
1) Alright i did it!!!!










2)




















Or you could do it as a picture


























3)This site has quite detailed steps on how to multiply with everything! Plus im combining two questions in one by saying it also has a dividing fractions section too with all the same cool stuff!!!

4)




















Now just with fractions...


























6) I nomonate Jennifer of 8-41 because she used very good pictures to explain her questions.
I nomonate Aldrin of 8-73 because he put his whole post on the scrolly thing and used alot of pictures.
I nomonate Dhona of 8-16 because she used pictures for most of her questions.
I nomonate Katho of 8-17 because of really cool pictures.

7) Well... Guess what time it is again!! Thats right!!! Its time for pie!!!
O.K. So one day I had 4 2/3 of a pie. Yay! I eat 1 4/5 of a pie. Yay! All of a sudden I find 2 1/2 pies under the couch!! Yay! Then i go and win a bet and my total amount of pies get multiplyed by 2 1/6!! Yay!! Then I think to myself I wonder how many groups of 6/7 I could make with all pie right now!!! Its your job to figure that out. Good luck, and I'd recomend using a calculator.
and yes i will try to animate this too!



Now I choose to answer Alex's question. (8-17)
If i drove a car for 1 1/4 hours at an average speed of 90km.How far did I get?
First gotta change 90 into a fraction by going 90/1
then change 1 1/4 into an improper fration 5/4
Can you see any cross reduction because i can't!
so...
5 x 90=450
4 x 1 = 4
now how many times does 4 go into 450???
112 times with 2/4 left (or 1/2)
final answer is that u would go 112 and 1/2 km

Scribe Thingy

Today in class we learned how to add fractions.

If the denominator is the same then you just add the numerator
EXAMPLE:

two fifths plus one fifth

2/5 + 1/5 = 3/5 (the denominator is the same)

When you dont have the same denominator you need to make equivelent fractions

Fraction Scribbler!!

Box 1:Parts of a fraction

Numerator
---------------
Denomenator

Box 2:

Denomenator-tells you how many equal sized parts make up the WHOLE.
-it is the bottom number in a fraction
-the denomenator tells you how large or small the parts are.

Box 3:
(a picture of a square with line in the middle)
halves 2=sized pieces

(picture of a square with 2 lines going down)
thirds 3=sized pieces

(picture of a square with a line going horizontally and 3 lines vertical)
eighths 4=sized pieces

As the denomenator gets larger the equal sized pieces get smaller.

Box 4:
Numerator-it is the top number in a fraction
-tells you how many parts of the whole you have
-when the numerator and denomenator are the same (4/4) you have 1 whole.
-when the numerator is larger than the denomenator it is an improper fraction. You have more than 1 whole.

Box 5:

(picture of square with line vertical and 1 half of it is shaded)
1 piece out of 2

(picture of square with 2 vertical lines and 2 thirds of it is shaded)
2 pieces out of 3

(picture of square with 1 horizontal line and 3 vertical lines, 3/8th of it is shaded)
3 pieces out of 8

(picture of square with 1 vertical and horizontal line, all shaded)
4/4 4 pieces out of 4 or 1 whole

5/4= (picture of square with 1 vertical and horizontal line, all shaded) and (picture of square 1 vertical and 1 horizontal, 1/4th of it is shaded)

Box 6: What is larger?

1/2 or 3/8?

(picture of square with vertical line and 1 half is shaded) (picture of square with 1 horizontal and 3 vertical lines, 3/8th of it is shaded)

Make an equivalent fraction

(picture of square with 1 horizontal and 3 vertical lines, 4/8th of it is shaded) (picture of square with 1 horizontal and 3 vertical lines, 3/8th of it is shaded)

4/8th is larger than 3/8th

volume of a trianglular PRISM!

To find the volume of a trianglular prism you need to multiply base times height times width and divded by 2. eg. If the base of a triangluar prism was 5 cm, height was 4 cm, and width was 10 cm it would look like this.

V=BxHxWx.5
V=5x4x10x.5
V=20x10x.5
V=30x.5
V=15 cm3
____________________________________________________________________
To find the TSA you do this. If the height was 10cm, base was 7cm, and width was 6cm.

1.TSA=height x base
TSA=10x7
TSA=70cm2 x 2 = 140cm2

2.TSA=Base x Width
TSA=7x6
TSA=42cm2 x 2 =84cm2

3.TSA=Height x Width
TSA=10x6
TSA=60cm2 x 2 = 120 cm2

I hope I didn't do it wrong.

Deannia's Scribe for a Cylinder

1.)Find the volume for a cylinder, if the diameter is 8 and the height is 25.
pi r2
3.14(4)(4)
3.14x50.24
50.24x25=1256
Volume is 1256cm3. (didn't know how to do the pi r2 thingy, like how to make it in the computer.)

2.)Find the total surface area for a cylinder. You first have to find the area then you have to find the circumfrence. Were the diameter is 8 and the height is 18.
A=pi r2
A=3.14(4)(4)
A=50.24cm2


C=pi d
C=3.14(8)
C=25.12cm2


You get the total surface area by timesing 25.12 times 18 which gets you 452.16. You would then add your area twice then you would add 452.16 to get your answer. It would look like this.
50.24+50.24+452.16=552.64cm2

S0 your TSA would be 552.64cm2.
