5. Now we have two simple equations:
1) 100%=5648.28
2) x%=1580
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%=5648.28/1580
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 1580 is what percent of 5648.28
