1. We assume, that the number 549.99 is 100% - because it's the output value of the task.
2. We assume, that x is the value we are looking for.
3. If 100% equals 549.99, so we can write it down as 100%=549.99.
4. We know, that x% equals 384.99 of the output value, so we can write it down as x%=384.99.
5. Now we have two simple equations:
1) 100%=549.99
2) x%=384.99
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%=549.99/384.99
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 384.99 is what percent of 549.99
