To do this, you need to find the lowest commen denominator of 1/3 and 1/5. The lowest common multiple of the two denominators, 3 and 5 is 15, so you convert each fraction to a fraction with a denominator of fifteen and then add the numerators:

(1/3) + (1/5)

=(5/15) + (3/15)

=(5+3)/15

=8/15

Therefore your answer is eight fifteenths.
