1. We assume, that the number 4045.12 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 4045.12, so we can write it down as 100%=4045.12.
4. We know, that x% equals 161.54 of the output value, so we can write it down as x%=161.54.
5. Now we have two simple equations:
1) 100%=4045.12
2) x%=161.54
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%=4045.12/161.54
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 161.54 is what percent of 4045.12

100%/x%=4045.12/161.54
(100/x)*x=(4045.12/161.54)*x       - we multiply both sides of the equation by x
100=25.04098056209*x       - we divide both sides of the equation by (25.04098056209) to get x
100/25.04098056209=x
3.9934538406772=x
x=3.9934538406772

now we have:
