1. We assume, that the number 21939 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 21939, so we can write it down as 100%=21939.

5. Now we have two simple equations:
1) 100%=21939
2) x%=6939
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%=21939/6939
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 6939 is what percent of 21939
