Question

In a zoo the ratio of giraffes to apes is 6 to 5 and the ratio of apes to zebras is 4 to 1. What is the minimum number of zebras the zoo could have? Please answer asap

Answer 1

5 Zebras

Explanation:

In the zoo, the ratio of Giraffes to Apes is 6 : 5

So, for 1 Ape there are
`(6)/(5)` Giraffes in the zoo.

Again, the ratio of Apes to Zebras in the zoo is 4 : 1.

So, for 1 Ape there are
`(1)/(4)` Zebras in the zoo.

Hence, the ratio of Giraffes to Apes to Zebras in the zoo is
`(6)/(5) : 1 : (1)/(4)`

Since, there are animals in whole number but not in fraction in the zoo, so the ratio in whole numbers is

`(6)/(5) * 20 : 1 * 20 : (1)/(4) * 20`

= 24 : 20 : 5

which is the most simplified whole number ratio of number of Giraffes, Apes and Zebras.

Therefore, there will be a minimum of 5 Zebras in the zoo. (Answer)
