1. We assume, that the number 3924.45 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 3924.45, so we can write it down as 100%=3924.45.
4. We know, that x% equals 315.46 of the output value, so we can write it down as x%=315.46.
5. Now we have two simple equations:
1) 100%=3924.45
2) x%=315.46
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%=3924.45/315.46
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 315.46 is what percent of 3924.45

(100/x)*x=(3924.45/315.46)*x       - we multiply both sides of the equation by x
100=12.440404488683*x       - we divide both sides of the equation by (12.440404488683) to get x
100/12.440404488683=x
8.0383238415574=x
x=8.0383238415574

now we have:
