18.24 is what percent of 19.8 - 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 19.8 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 19.8, so we can write it down as 100%=19.8.
4. We know, that x% equals 18.24 of the output value, so we can write it down as x%=18.24.
5. Now we have two simple equations:
1) 100%=19.8
2) x%=18.24
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%=19.8/18.24
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 18.24 is what percent of 19.8

100%/x%=19.8/18.24
(100/x)*x=(19.8/18.24)*x       - we multiply both sides of the equation by x
100=1.0855263157895*x       - we divide both sides of the equation by (1.0855263157895) to get x
100/1.0855263157895=x
92.121212121212=x
x=92.121212121212

now we have:
18.24 is 92.121212121212% of 19.8
