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

1. We assume, that the number 4878.4 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 4878.4, so we can write it down as 100%=4878.4.
4. We know, that x% equals 4382.4 of the output value, so we can write it down as x%=4382.4.
5. Now we have two simple equations:
1) 100%=4878.4
2) x%=4382.4
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%=4878.4/4382.4
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 4382.4 is what percent of 4878.4

100%/x%=4878.4/4382.4
(100/x)*x=(4878.4/4382.4)*x       - we multiply both sides of the equation by x
100=1.1131799926981*x       - we divide both sides of the equation by (1.1131799926981) to get x
100/1.1131799926981=x
89.832732043293=x
x=89.832732043293

now we have:
