To get the solution, we are looking for, we need to point out what we know.

1. We assume, that the number 15013.04 is 100% - because it's the output value of the task.
2. We assume, that x is the value we are looking for.
3. If 100% equals 15013.04, so we can write it down as 100%=15013.04.
4. We know, that x% equals 12920.4 of the output value, so we can write it down as x%=12920.4.
5. Now we have two simple equations:
1) 100%=15013.04
2) x%=12920.4
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%=15013.04/12920.4
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 12920.4 is what percent of 15013.04

100%/x%=15013.04/12920.4
(100/x)*x=(15013.04/12920.4)*x       - we multiply both sides of the equation by x
100=1.1619640258816*x       - we divide both sides of the equation by (1.1619640258816) to get x
100/1.1619640258816=x
86.061184143918=x
x=86.061184143918

now we have:
