5. Now we have two simple equations:
1) 100%=12513
2) x%=9891.59
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%=12513/9891.59
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 9891.59 is what percent of 12513
