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

1. We assume, that the number 639.88 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 639.88, so we can write it down as 100%=639.88.
4. We know, that x% equals 461.8 of the output value, so we can write it down as x%=461.8.
5. Now we have two simple equations:
1) 100%=639.88
2) x%=461.8
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%=639.88/461.8
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 461.8 is what percent of 639.88

100%/x%=639.88/461.8
(100/x)*x=(639.88/461.8)*x       - we multiply both sides of the equation by x
100=1.3856214811607*x       - we divide both sides of the equation by (1.3856214811607) to get x
100/1.3856214811607=x
72.169781834094=x
x=72.169781834094

now we have:
