An animal shelter houses cats, rabbits, and ferrets. There are 108 animals at the shelter. Of the animals, one third are cats. Three fourths of the remaining animals are rabbits. How many of the animals are ferrets?

18 ferrets

Step-by-step explanation:

From the statement you can write the following:

c+r+f= 108

c=cats

r= rabbits

f= ferrets

Then, you have that one third of the animals are cats:

c= 108*(1/3)= 36

Next, three fourths of the remaining animals are rabbits:

r= (108-36)*(3/4)= 72*(3/4)= 54

Now, as you have determine the amount of cats and rabbits, you can isolate f and find the amount of ferrets:

f=108-c-r

f=108-36-54

f= 18

According to this, the answer is that there are 18 ferrets.
