at the zoom,the ratio of monkeys to gorrillas is 5:2 if there were 20 monkeys how many gorrilas would there be?

Umnica [9.8K]

8 gorrilas

Explanation:

The ratio of monkeys to gorrila = 5:2

This means there are 5 monkeys for every 2 gorrilas

when there are 20 monkeys,

let the number of gorrilas = x

5 monkeys = 2 gorrilas

20 monkeys = x

cross multiply:

5(x) = 20(2)

5x = 40

divide both sides by 5:

5x/5 = 40/5

x = 8

Hence, if there were 20 monkeys, we would have 8 gorrilas.
