5. Now we have two simple equations:
1) 100%=531.87
2) x%=543.87
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%=531.87/543.87
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 543.87 is what percent of 531.87
