Question

The ratio of cats to dogs to vermin is 1:2:7. If there are 28 vermin in total, how many cats are there? How many dogs? How many animals in total?

Answer 1

Cats = 8

Dogs = 4

Explanation:

Ratio = 1:2:7

So, Vermin = 28

So, 1x = Dogs

2x = Cats

7x = 28

x = 28/7 = 4

So x = 4

So cats = 2x4 = 8

So dogs = 1x4 = 4

So 4:8:28 = 1:2:7
