5. Now we have two simple equations:
1) 100%=3962.51
2) x%=2109.78
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%=3962.51/2109.78
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 2109.78 is what percent of 3962.51
