At a kennel, the ratio of dogs to cats was 4to9. if there were 64 dog s how many cats were there

Dogs. Cats.

4. To. 9

64. To.?

I solved this by guess-timating, and i got it right. I know that 8*8=64 and 4*2=8 8*2=16, and i checked and got 16*4=64.

Since you do:

Dogs:4 * 16 = 64

You have to do:

Cats:9 * 16 = # of cats

And 9*16=144,

So there are 144 cats at the kennel
