The first thing you want to do is get a common denominator. This means the number at the bottom of both fractions is the same.
In this problem it would be fifteen
2/5 x 3/3 = 6/15
1/3 x 5/5 = 5/15
When adding fractions you only add the numerators or the top numbers together. When adding fractions the denominator is NEVER ADDED.
6/15 + 5/15 = 11/15
