Question

An animal shelter houses dogs​, cats​, and ferrets. There are 144 animals at the shelter. Of the​ animals, one fourth are dogs. Eight ninths of the remaining animals are cats. How many of the animals are ferrets​?

Answer 1

12

Explanation:

1 - 1/4 = 3/4 (remaining animals which are cats and ferrets)

1 - 8/9 = 1/9 (means 1/9 of the remaining animals are ferrets)

1/9 x 3/4 = 1/12 (means 1/12 of the animals are ferrets)

1/12 x 144 = 12 ferrets
