So basically, all you need to do is add the two fractions: 1/2 & 1/3.
If you do not not know how to add fractions, all you need to do is find a common denominator. In this case, the common denominator is 6. Now, the question becomes:
3/6 + 2/6 =
5/6
I'm sorry if I did not clarify this well,
Hope this helps and correct me if I am wrong!
