21 is what percent of 16725 - step by step solution

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

1. We assume, that the number 16725 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 16725, so we can write it down as 100%=16725.
4. We know, that x% equals 21 of the output value, so we can write it down as x%=21.
5. Now we have two simple equations:
1) 100%=16725
2) x%=21
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%=16725/21
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 21 is what percent of 16725

100%/x%=16725/21
(100/x)*x=(16725/21)*x       - we multiply both sides of the equation by x
100=796.42857142857*x       - we divide both sides of the equation by (796.42857142857) to get x
100/796.42857142857=x
0.12556053811659=x
x=0.12556053811659

now we have:
21 is 0.12556053811659% of 16725
