5. Now we have two simple equations:
1) 100%=449.99
2) x%=287.99
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%=449.99/287.99
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 287.99 is what percent of 449.99
