21 is what percent of 25029 - 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 25029 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 25029, so we can write it down as 100%=25029.
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%=25029
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%=25029/21
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 25029

100%/x%=25029/21
(100/x)*x=(25029/21)*x       - we multiply both sides of the equation by x
100=1191.8571428571*x       - we divide both sides of the equation by (1191.8571428571) to get x
100/1191.8571428571=x
0.083902672899437=x
x=0.083902672899437

now we have:
21 is 0.083902672899437% of 25029
