5. Now we have two simple equations:
1) 100%=934.87
2) x%=819.87
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%=934.87/819.87
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 819.87 is what percent of 934.87
