Question

A library had 7240 books, of which 1780 are economics books, and the rest are literature books. What is the ratio of the number of literature books to the number of economics books.

(Write fraction in the lowest term)

Answer 1

362 : 89

Explanation:

We can simplify the ratio 7240 : 1780 by dividing both terms by the greatest common factor (GCF).

The GCF of 7240 and 1780 is 20.

Divide both terms by 20.

7240 ÷ 20 = 362

1780 ÷ 20 = 89

Therefore:

7240 : 1780 = 362 : 89
