inches.

Answer 1

1 2/15 inches

Explanation:

First you need to make the denominator of the two fractions match.

4/5 and 1/3

the least common multiple of these is 15

4/5 becomes 12/15

1/3 becomes 5/15

add them together

17/15

subtract 15 from 17 because 15/15 is one

we get 2

put 2 as the numerator and 15 as the denominator
