Question

What is 2/5 +1/3= show your work

Answer 1

Must find a common denominator

2/5 + 1/3

= 6 + 5/15
= 11/15

Answer 2

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
