Q:
# Draw a model to support the following statement:3 1/2 divided by 2/3Look at the document also:

Accepted Solution

A:

part 2....lol....I 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 + 1/4....common 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.Β

3/4 - 2/3....common denominator is 12

9/12 - 8/12 =

1/12

====================

2/3 * 3/8......multiply straight across.....numerator 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

5/6 + 1/4.
