5. Now we have two simple equations:
1) 100%=12144.64
2) x%=66.81
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%=12144.64/66.81
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 66.81 is what percent of 12144.64
