@ChrisR
I believe there is a problem with all of the tests except Test 2.
I can get Test 2 accepted when using the following formula:
(a * n + b) / (n * (n + m)) * (u^n / v^n)
Have I interpreted the equation incorrectly?
Thanks,
George Berken

Thanks, Christian!

George, thanks for pointing out the errors. Please hold on working on this problem while I correct it.

OK, try the problem now. I found a sign error in my work, and I checked the answers independently. What could possibly go wrong now? :-)

Chris,
Yes, it seems to be working now. I thought it was I that had the sign error!
