The answer is 3/5
the problem has the same denominator so you just add the numerator but lets say it was 2/3 + 4/5 you have to find an equal denominator so 15 would be the denominator

2/3
+
4/5

3*5=15
2*5=10

5*3=15
4*3=12

10/15 + 12/15 = 22/15

would be an example if the denominators were different
