4/15 of the 315 members of a book club are male. how many members r female?

A.) 131

B.) 231

C.) 174

D.) 84

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
