A college has a student to teacher ratio of 30 to 2. If there are 190 teachers at the college, how many students attend the college

OpenStudy (nerdgirl):

I'm not going to give you the answer, but I'll tell you how to do it. Write this out and solve by cross-multiplying: 2/30 * x/190

OpenStudy (nerdgirl):

Pardon me: it should be written 30/2 * 190/x
