**Ms. Sue**, Tuesday, November 30, 2010 at 2:45pm7/10 of the books are not small.

3/10x = 12

x = 12 / (3/10)

x = 12 * (10/3)

x = 120/3

x = 40

**prakash**, Tuesday, November 30, 2010 at 2:49pmlet, total number of books= X

Small= 12

Remaining books = X-12

now,the remaining books comprise:

1/2X= Medium

2/10X= Large

Therefore,

1/2X+2/10X=X-12

Solve for X and you will get the answer!!
