sachelles growing fraction post

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.

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.
