5. Now we have two simple equations:
1) 100%=8539.12
2) x%=1691.34
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%=8539.12/1691.34
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 1691.34 is what percent of 8539.12
