5. Now we have two simple equations:
1) 100%=765.42
2) x%=661.28
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%=765.42/661.28
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 661.28 is what percent of 765.42
