2/3 + 4/5

The common denominator is 3 x 5 = 15

To complete the addition you MUST change the numerators (top) to the equivalent values.

2/3 = 2(5) / 3(5) = 10/15

4/5 = 4(3) /5(3) = 12/10

Hence 2/3 + 4/5 = 10/15 + 12/15

Add the numerators

22/15

Convert back to a mixed number.

1 7/15 The answer!!!!!
