5. Now we have two simple equations:
1) 100%=525.44
2) x%=689.64
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%=525.44/689.64
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 689.64 is what percent of 525.44
