The ratio of 8 less than a number to 28 more than that number is 2 to 5. What is the number?

OpenStudy (anonymous):

Write out your equations: (x-8) (x+28) Put them in the ratio: 5(x-8)=2(x+28) Multiply it out and solve: x=33

Thanks but I figured it and it's actually 32! :)

Oops! My mental math is rusty. 96/3 is not 33. I knew that. ;) But I'm glad you got it!
