39.2 is what percent of 54.07 - 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 54.07 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 54.07, so we can write it down as 100%=54.07.
4. We know, that x% equals 39.2 of the output value, so we can write it down as x%=39.2.
5. Now we have two simple equations:
1) 100%=54.07
2) x%=39.2
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%=54.07/39.2
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 39.2 is what percent of 54.07

100%/x%=54.07/39.2
(100/x)*x=(54.07/39.2)*x       - we multiply both sides of the equation by x
100=1.3793367346939*x       - we divide both sides of the equation by (1.3793367346939) to get x
100/1.3793367346939=x
72.498612909192=x
x=72.498612909192

now we have:
39.2 is 72.498612909192% of 54.07
