Homework Help: Math

Posted by David on Monday, April 26, 2010 at 6:40pm.

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
