Alisson Kirby · Answer 1

5/8 of the cast does not have to sing. You find this by doing 8/8 - 5/8

Stafford · Answer 2

3/8 has to sing

8/8 is all

all=haveto+don'thaveto

all=8/8

haveto=3/8

subsitute

8/8=3/8+don'thaveto

subtract 3/8 from both sides

8/8-3/8=5/8

5/8=don'thavetosing

answer is 5/8
