7 9/10

Explanation:

Find the LCM (Least Common Multiple) on the denominator. Here, the LCM is 10. Then you have to divide 10 by 5 to change the first fraction.

10 /5 = 2

Next, multiply that by 3 to get 6. Now you have the fractions

2 6/10" " and " "5 3/10

Adding that, you add the numerators and copy the denominators. Then add the whole numbers. You get

(2+5) ((6 + 3))/10 = 7 9/10
