Question

4/15 of the 315members of a book club are males, how many in the group are females

Answer 1

If 4/15 are males, then you can assume that the rest (11/15) are females.

Find what is 11/15 if 315 using a proportion.

11 f
— = —
15 315


In this proportion, multiply 15 by 21 to get 315, so multiply 11 by 21 to get 231, which is the value of F.


Therefore, f=231. In other words, there are 231 females in the book club.

Hope this helps!
