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

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.
