I have the answer but I can't get to the answer for some reason. I think I must be doing something wrong. 1) 9/y=3/4 I did 1/9 * 9/y=3/4*1/9 y=1/12 but the answer in the book says it should be 12.

you need to cross multiply 9*4=y*3 36=3y divide both sides by 3 y=12 not a math person but I am pretty sure this is the correct way to solve. I think this is set up like a ratio.

9/y = 3/4 1/9 * 9/y = 3/4 * 1/9 1/y = 3/36 = 1/12 You aren't done yet, you have 1/y not y. Take the reciprocal of both sides. y = 12

Well I got the rest of the questions in that section right! YIPPIE. I'm on section two of chapter five. I have two more weeks to study for this test that I really dont' feel like taking at all.

Like I tell my students... There is more than one way to skin a cat. I like the idea of solving this problem as a proportion in this case. Solving the problem just comes down to multiplying two integers then dividing by an integer.
