21188.92 is what percent of 90000 - 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 90000 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 90000, so we can write it down as 100%=90000.
4. We know, that x% equals 21188.92 of the output value, so we can write it down as x%=21188.92.
5. Now we have two simple equations:
1) 100%=90000
2) x%=21188.92
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%=90000/21188.92
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 21188.92 is what percent of 90000

100%/x%=90000/21188.92
(100/x)*x=(90000/21188.92)*x       - we multiply both sides of the equation by x
100=4.2475029402159*x       - we divide both sides of the equation by (4.2475029402159) to get x
100/4.2475029402159=x
23.543244444444=x
x=23.543244444444

now we have:
21188.92 is 23.543244444444% of 90000
