21 is what percent of 5027 - 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 5027 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 5027, so we can write it down as 100%=5027.
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%=5027
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%=5027/21
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 5027

100%/x%=5027/21
(100/x)*x=(5027/21)*x       - we multiply both sides of the equation by x
100=239.38095238095*x       - we divide both sides of the equation by (239.38095238095) to get x
100/239.38095238095=x
0.41774418142033=x
x=0.41774418142033

now we have:
21 is 0.41774418142033% of 5027
