Question

There are 1/4 as many adults as children at a concert.
(A) What is the ratio of the number of children to the number of adults?
(B) How many times is the number of children compared to the number of adults?

Answer 1

Let the number of children be x.

Number of adults at the concert = $\frac{1}{4} *x$ (as given there are 1/4 as many adults as children at a concert.)

(A). Ratio of number of children to number of adults = $\frac{x}{\frac{x}{4}}$

= $\frac{4x}{x}$

= 4

Hence, the ratio of the number of children to the number of adults = 4:1

(B). Since the ratio between number of children to the number of adults is 4:1

Hence, number of children wil be 4 times the number of adults.
