5. Now we have two simple equations:
1) 100%=3541.67
2) x%=685.79
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%=3541.67/685.79
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 685.79 is what percent of 3541.67
