Efficiency

Hello,
This might be a silly question...but I got it incorrect on a question.

How do you calculate the ' percentage efficiency of a transmission line ' .

Any example...or just the method even.
Thanks!  :)

I thought would go on the numerator?

That's what I think as well. The point of an efficiency % is that it gets higher as the system gets more efficient.
