1 answer

To add fractions, we need to find a common denominator. In this case, the common denominator is 15.

Converting the fractions to have a denominator of 15:

4/5 = (4/5) * (3/3) = 12/15
7/15 = (7/15) * (1/1) = 7/15
3/5 = (3/5) * (3/3) = 9/15

Adding the fractions:

12/15 + 7/15 + 9/15 = (12 + 7 + 9)/15 = 28/15

Therefore, 4/5 + 7/15 + 3/5 = 28/15.
