Question

A librarian put 33 books back on the shelves before lunch. Of the books, 11 were non-fiction. What is the ratio of the number of non-fiction books to the total number of books the librarian put away before lunch?

Answer 1

Explanation:

Number of non fiction books = 11

Total number of books = 33

11:33 = 1 : 3

11 goes into 33 three times.
