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
