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

1. We assume, that the number 315738 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 315738, so we can write it down as 100%=315738.
4. We know, that x% equals 21202 of the output value, so we can write it down as x%=21202.
5. Now we have two simple equations:
1) 100%=315738
2) x%=21202
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%=315738/21202
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 21202 is what percent of 315738

100%/x%=315738/21202
(100/x)*x=(315738/21202)*x       - we multiply both sides of the equation by x
100=14.89189699085*x       - we divide both sides of the equation by (14.89189699085) to get x
100/14.89189699085=x
6.7150612216458=x
x=6.7150612216458

now we have:
