Answer:
11
Explanation:
3/7r + 5/8s
r = 14
s = 8
3/7 x 14 + 5/8 x 8
3/7 x 14 = 6
5/8 x 8 = 5
6 + 5 = 11
ok so it's like the 3/7 and 5/8 are fractions so you just multiply each one by the number their next you which in this case is r and s so it's like you're just multiplying a fraction and a number. does that make since?
