To get the solution, we are looking for, we need to point out what we know.

1. We assume, that the number 548.73 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 548.73, so we can write it down as 100%=548.73.
4. We know, that x% equals 390.65 of the output value, so we can write it down as x%=390.65.
5. Now we have two simple equations:
1) 100%=548.73
2) x%=390.65
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%=548.73/390.65
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 390.65 is what percent of 548.73

100%/x%=548.73/390.65
(100/x)*x=(548.73/390.65)*x       - we multiply both sides of the equation by x
100=1.4046589018303*x       - we divide both sides of the equation by (1.4046589018303) to get x
100/1.4046589018303=x
71.1916607439=x
x=71.1916607439

now we have:
