What equal to 1/2+1/3

The answer would be 2/5

The tops are numerators, the bottoms are denominators. All you do is add the numerators together, and then add the denominator on top. The answer to the numerator goes on the top, the answer to the denominator goes on the bottom.

2/5 because if u add the numerators together u get 2 and when u add the dominators together u get 5
