5. Now we have two simple equations:
1) 100%=1583.34
2) x%=1277.55
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%=1583.34/1277.55
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 1277.55 is what percent of 1583.34
