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!

There is a type of ammo in f/o/r/t/n/i/t/e that can be magically used for every single gun. You open an ammo box, and out pops 141 rounds of that ammo. You have already collected 6 guns. How many rounds go into each gun?

The answer is 23.5

THERE IS A REMAINDER??

Nothing happens! Literally! It never happened! There is no ammo that can be used for all the guns. GG and hope to see you on the game sometime, cause...i am not allowed to have it.
