1. We assume, that the number 4377.64 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 4377.64, so we can write it down as 100%=4377.64.
4. We know, that x% equals 87.55 of the output value, so we can write it down as x%=87.55.
5. Now we have two simple equations:
1) 100%=4377.64
2) x%=87.55
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%=4377.64/87.55
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 87.55 is what percent of 4377.64

100%/x%=4377.64/87.55
(100/x)*x=(4377.64/87.55)*x       - we multiply both sides of the equation by x
100=50.001599086236*x       - we divide both sides of the equation by (50.001599086236) to get x
100/50.001599086236=x
1.9999360385961=x
x=1.9999360385961

now we have:
