Question

If 48 of the 92 people who swim at the YMCA are children, what is the ratio of children to adults who swim at the YMCA? Write the ratio in lowest terms as a fraction or with a colon.

Answer 1

12 : 11

Explanation:

If the people who are not children are adults, then the ratio of children to adults is ...

children : adults = 48 : (92 -48) = 48 : 44 = (4·12) : (4·11) = 12 : 11

Answer 2

12/11

Explanation:

If 48 of 92 are children, then:

92 - 48 = 44 are the adults.

The ratio children to adults is:

48 children : 44 adults

48/44 = 12/11
