18.09 is what percent of 67.5 - 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 67.5 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 67.5, so we can write it down as 100%=67.5.
4. We know, that x% equals 18.09 of the output value, so we can write it down as x%=18.09.
5. Now we have two simple equations:
1) 100%=67.5
2) x%=18.09
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%=67.5/18.09
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 18.09 is what percent of 67.5

100%/x%=67.5/18.09
(100/x)*x=(67.5/18.09)*x       - we multiply both sides of the equation by x
100=3.7313432835821*x       - we divide both sides of the equation by (3.7313432835821) to get x
100/3.7313432835821=x
26.8=x
x=26.8

now we have:
18.09 is 26.8% of 67.5
