**Celina**, Thursday, November 20, 2008 at 4:57pmBy what you said in the problem, I think you are trying to find a percent. In this case, you could set up an eqaution. Do you know cross multiplication. Well, just in case you don't, I'll show you.

x/100 = 1.20/2.25

Then what you would do is multiply 1.20 by 100, then divide by 2.25.

And there's your answer!

Hope I helped!

**Ms. Sue**, Thursday, November 20, 2008 at 5:00pmAnother way to solve this problem:

2.25 - 1.20 = 1.05

1.05 / 1.2 = 0.875 = 87.5%
