A set of books fills a shelf that is 24in long each book is 3/4 inch thick. How many books are in the classroom shelf?
Would it be 18 ???

No, divide 24 by 3/4. remember you need to multiply by the opposite of the fraction so it is 24 times 4 and dived by 3 :)
answer:32

24 / (3/4)
(24/1) * (4/3) = 96/3 = 32 books
