5. Now we have two simple equations:
1) 100%=128109
2) x%=61117.5
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%=128109/61117.5
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 61117.5 is what percent of 128109
