In a zoo the ratio of giraffes to apes is 6 to 5 and the ratio of apes to zebras is 8 to 1. What is the minimum number of zebras the zoo could have?

Say we have 48 giraffes and 40 apes

THen we would have 5 zebras

The GCD of these numbers is 1, so we cant simplify these numbers anymore

SO the zoo has 5 zebras

Heres another way to do it MooMooooMooM:

We know that the numero of apes must have factors of 4 and 5

20 is the smallest number that has these factors,

the smallest number of zebras is 5.
