4. We know, that x% equals 1239.5 of the output value, so we can write it down as x%=1239.5.
5. Now we have two simple equations:
1) 100%=8171.65
2) x%=1239.5
where left sides of both of them have the same units, and both right sides have the same units, so we can do something like that:
100%/x%=8171.65/1239.5
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 1239.5 is what percent of 8171.65
