5. Now we have two simple equations:
1) 100%=17545.31
2) x%=121.5
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%=17545.31/121.5
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 121.5 is what percent of 17545.31
