5. Now we have two simple equations:
1) 100%=1445.53
2) x%=391.66
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%=1445.53/391.66
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 391.66 is what percent of 1445.53
