Question

At a local bookstore, the ratio of nonfiction to fiction books is 3:5. If the bookstore recieves an shipment with 27 nonfiction books, how many fiction books can be excepted in the shipment?

Answer 1

Set up a proportion for this problem

non-fiction to fiction = 3/5

If he gets 27 non- fictions, you can set up a proportion.

3/5 = 27/x           Cross multiply

3x  = 5 * 27         Divide by 3

x = 5 * 27/3         Divide

x = 5 * 9

x = 45

Answer: There should be 45 fiction books.
