39.57 is what percent of 124.36 - 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 124.36 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 124.36, so we can write it down as 100%=124.36.
4. We know, that x% equals 39.57 of the output value, so we can write it down as x%=39.57.
5. Now we have two simple equations:
1) 100%=124.36
2) x%=39.57
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%=124.36/39.57
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 39.57 is what percent of 124.36

100%/x%=124.36/39.57
(100/x)*x=(124.36/39.57)*x       - we multiply both sides of the equation by x
100=3.1427849380844*x       - we divide both sides of the equation by (3.1427849380844) to get x
100/3.1427849380844=x
31.818912833709=x
x=31.818912833709

now we have:
39.57 is 31.818912833709% of 124.36
