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

1. We assume, that the number 1989.39 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 1989.39, so we can write it down as 100%=1989.39.
4. We know, that x% equals 99.47 of the output value, so we can write it down as x%=99.47.
5. Now we have two simple equations:
1) 100%=1989.39
2) x%=99.47
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%=1989.39/99.47
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 99.47 is what percent of 1989.39

100%/x%=1989.39/99.47
(100/x)*x=(1989.39/99.47)*x       - we multiply both sides of the equation by x
100=19.999899467176*x       - we divide both sides of the equation by (19.999899467176) to get x
100/19.999899467176=x
5.0000251333323=x
x=5.0000251333323

now we have:
