Question

1,935 people visit a library during one week

The ratio children: adults is 1:4
How many more adults than children visited the library?

Answer 1

1161

Explanation:

The ration is 1:4 so that means out of 5 people (1 + 4 = 5) there is 1 child and 4 adults. 1935 ÷ 5 = 387 groups of 5 people.

387 x 1 = 387 children

387 * 4 = 1548 adults

So we do 1548-387=1161 more adults than children.
