Question

At a small zoo, 30% of the animals are reptiles. If there are 135 reptiles, how many total animals are at the zoo?

Answer 1

450 reptiles

Explanation:

Let's say all the reptiles are represented by x.

30% of x would be 0.3x

So 0.3x = 135

If we divide both sides by 0.3 we get:

0.3x/0.3 = 135/0.3

x = 450 reptiles
