Draw a model to support the following statement:
3 1/2 divided by 2/3

look at the document also:

Part 2lolI cant draw a model.

5/6 + 1/4.
steps involved : find a common denominator. Make both fractions have that denominator by converting them. Add fractions. Turn to mixed numbers if necessary.

5/6 + 1/4common denominator 12
10/12 + 3/12 =
13/12 or 1 1/12

I dont know what to put foe reasoning other then that you can't add/subtract fractions unless they have the same denominator.

3/4 - 2/3

steps involved: find the common denominator to both fractions. Convert both fractions so they have the same denominator. Subtract them. 

3/4 - 2/3common denominator is 12
9/12 - 8/12 =
1/12


2/3 * 3/8multiply straight acrossnumerator with numerator, denominator with denominator. Reduce when needed.

2/3 * 3/8 = (2 * 3) / (3 * 8) = 6/26 reduces to 1/4

with multiplication / division of fractions, common denominators are not necessary

(3/8) / (3/4) =
3/8 * 4/3 =
12/24 reduces to 1/2

when dividing with fractions, u flip what u r dividing by, then multiply
