540.08 is what percent of 392.5 - 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 392.5 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 392.5, so we can write it down as 100%=392.5.
4. We know, that x% equals 540.08 of the output value, so we can write it down as x%=540.08.
5. Now we have two simple equations:
1) 100%=392.5
2) x%=540.08
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%=392.5/540.08
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 540.08 is what percent of 392.5

100%/x%=392.5/540.08
(100/x)*x=(392.5/540.08)*x       - we multiply both sides of the equation by x
100=0.72674418604651*x       - we divide both sides of the equation by (0.72674418604651) to get x
100/0.72674418604651=x
137.6=x
x=137.6

now we have:
540.08 is 137.6% of 392.5
