18.23 is what percent of 20915000 - 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 20915000 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 20915000, so we can write it down as 100%=20915000.
4. We know, that x% equals 18.23 of the output value, so we can write it down as x%=18.23.
5. Now we have two simple equations:
1) 100%=20915000
2) x%=18.23
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%=20915000/18.23
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 18.23 is what percent of 20915000

100%/x%=20915000/18.23
(100/x)*x=(20915000/18.23)*x       - we multiply both sides of the equation by x
100=1147284.6955568*x       - we divide both sides of the equation by (1147284.6955568) to get x
100/1147284.6955568=x
8.7162323691131E-5=x
x=8.7162323691131E-5

now we have:
