Question

at a kennel, the ratio of dogs to cats was 4 to 9. If there were 64 dogs, how many cats were at the kennel?

Answer 1

The ratio of dogs to cats is 4 to 9. That means the number of cats divided by the number of dogs is equal to (4/9).

So C/D = 4/9
D = 64. Substitute and solve for C.

Answer 2

4:9 ::d:c
4:9 :: 64:c
4c=9*64
c =9*16=144

That way you don't have a fraction of a cat
