The answer would be 15 4/5. This is because 9 + 6 is 15, and 5/10 + 3/10 is 8/10. We can add these two fractions together because they have the same denominator. So it would be 15 8/10, and 8/10 simplified would be 4/5(because i divided 8 and 10 by the same number until they can't be divided by a whole number anymore). So the answer would be 15 4/5, I hope this helped :)
