Answer:

24 Cats.

Step-by-step explanation:

You can set up an inequality of 21/18 and 28/x.

Multiply 18 and 28, you get 504. Divide 504 by 21 and you get your answer of 24.
25 cats because if you see the difference between cats and dogs it is 3 keeping the same ratio would mean subtract 3 from 28 therefore the answer is 25
