Question

What is 1/3 added to 5/6

Answer 1

7/6
Change 1/3 to 2/6 in order to have a common denominator.
Then add the numerators (2 and 5) and keep the denominator. <span />

Answer 2

The first thing to do is to make the denominators.  Since 3 goes into 6, the first fraction should simply be doubled: 
1/3 + 5/6 = 2/6 + 5/6
5 + 2 = 7
7/6

1/3 + 5/6 = 1 1/6 or 7/6
