Hi there!

First we rearrange the sum in order to add both of the fractions first. We can rearrange because the only thing we need to do is adding.

Add the fractions.
** If you don't get this, think of this story: you lack 1/3 of an apple pie and someone gives you 2/3 of pie. How much pie do you have left?
- 1 / 3 + 2 / 3 = 1 / 3 **

Finally add 4 to our found fraction.

Therefore, the answer is 4 1/3.
