Question

The ratio of boys to girls in a senior class is 5:3. If 9/10 of the boys may graduate, what is the maximum part of the senior class that may graduate?

a- 3/5
b- 7/8
c- 15/16
d- 2/3
e- 27/50

Answer 1

5/8 of the class is boys.
9/10 of 5/8 = 9/16
That is the boy part of the class. The girl part is 3/8
Add 9/16 and 3/8 to get the maximum part that may graduate.

Answer 2

15/16, so it's C.

Answer 3

yep
