m+f=315
m=4*315/15
m=1260/15
m=84

f=315-84
f=231

Corect answer : B
B) 231

To get the answer, you first need to figure out how many men are in the book club:
- Multiply the total number of members (315) by the fraction of members that are men (4/15)
- (4/15) * 315
- Multiply 4 by 315, and then divide by 15.
- This will give you the number of men (84)

Then you need to figure out how many women there are:
- Subtract the number of men (84) from the total number of members (315)
- 315 total members - 84 male members = 231 female members
