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

1. We assume, that the number 8639.09 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 8639.09, so we can write it down as 100%=8639.09.
4. We know, that x% equals 13.34 of the output value, so we can write it down as x%=13.34.
5. Now we have two simple equations:
1) 100%=8639.09
2) x%=13.34
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%=8639.09/13.34
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 13.34 is what percent of 8639.09

100%/x%=8639.09/13.34
(100/x)*x=(8639.09/13.34)*x       - we multiply both sides of the equation by x
100=647.60794602699*x       - we divide both sides of the equation by (647.60794602699) to get x
100/647.60794602699=x
0.15441441170308=x
x=0.15441441170308

now we have:
