If the ratio of cats to dogs is 2:3 and there are 18 dogs, how many cats are there?

Explanation

Since the ratio of cats to dogs is 2:3, we can write:

Number of cats / Number of dogs = 2/3

We know there are 18 dogs, so:

Number of cats / 18 = 2/3

Cross-multiply:

Number of cats = (2/3) × 18

Simplify:

Number of cats = 2 × 6

Number of cats = 12

So, there are 12 cats.
