At the National Zoo, 12 out of 25 exhibits contain a mammal. Assuming that there are 375 exhibits, how many many are mammals?

A) 11
B) 32
C) 132
D) 300

Here is what I am doing:

12/25 = x/375

375 * (12/25) = (x/375) * 375

180 = x

But 180 isn't an option

1 answer

I got 180 also.

Also -- 12/25 is almost 1/2. Half of 375 = 187.5 -- which makes 180 a logical answer. Since none of your choices comes close -- it's possible that the question contains an error.
