18.18 is what percent of 21510 - 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 21510 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 21510, so we can write it down as 100%=21510.
4. We know, that x% equals 18.18 of the output value, so we can write it down as x%=18.18.
5. Now we have two simple equations:
1) 100%=21510
2) x%=18.18
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%=21510/18.18
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 18.18 is what percent of 21510

100%/x%=21510/18.18
(100/x)*x=(21510/18.18)*x       - we multiply both sides of the equation by x
100=1183.1683168317*x       - we divide both sides of the equation by (1183.1683168317) to get x
100/1183.1683168317=x
0.084518828451883=x
x=0.084518828451883

now we have:
18.18 is 0.084518828451883% of 21510
