Question

The ratio of cats to horses on a farm is 1:3. If there are 12 horses, how many cats are there?

Answer 1

4 cats

Explanation:

a ratio of 1 : 3 means that there are 3 times more horses than cats, or that for every cat there are 3 horses.

so, if we have 12 horses, we have 3 times less cats, and so we can divide 12 by 3 which gives 4.

thus, we have 4 cats.
