Answer:
Add or subtract the following similar franction's. simplify or reduce you're answer into simplestl form
4/15 + 2/15
= 6/15 ÷ 3
= 2/5
4/7 + 3/7
= 7/7 or 1 whole
7/9 + 5/9
= 12/9 ÷ 3
= 4/3
4÷3 = 1 remainder 1
Therefore 4/3 = 1 1/3
3/5 - 1/5
= 2/5
9/12 - 5/12
= 4/12 ÷ 4
= 1/3
Find the sum or diffrence of the following dissimilar fraction's. express you're answer in simplest form
4/5 + 2/3
= 4x3/5x3 + 2x5/3x5
= 12/15 + 10/15
= 22/15
= 1 7/15
1/6 + 4/5
= 1x5/6x5 + 4x6/5x6
= 5/30 + 24/30
= 29/30
5/6 - 2/3
= 5/6 - 2x2/3x2
= 5/6 - 4/6
= 1/6
1/2 - 1/5
= 1x5/2x5 - 1x2/5x2
= 5/10 - 2/10
= 3/10
7/12 + 3/4
= 7/12 + 3x3/4x3
= 7/12 + 9/12
= 16/12
= 1 4/12 ÷ 4
= 1 1/3
