Do you mean: 2/3+5/8 If so: 2/3+5/8 = 16/24+15/24 = 31/24 or 1 and 7/24
First, find the least common multiple of 5 and 8 so that you convert both numbers to fractions with the same denominator. The least common multiple of 5 and 8 is 40, since their greatest common factor is 1. To convert 2/5 to ?/40 , multiply by 8/8 , so 2/5 x 8/8 = 16/40. To convert 5/8 to ?/40 , multiply by 5/5 , so 5/8 x 5/5 = 25/40. Now, you can perform the desired operation on the two fractions.
