52.5 is what percent of 40.31 - 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 40.31 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 40.31, so we can write it down as 100%=40.31.
4. We know, that x% equals 52.5 of the output value, so we can write it down as x%=52.5.
5. Now we have two simple equations:
1) 100%=40.31
2) x%=52.5
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%=40.31/52.5
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 52.5 is what percent of 40.31

100%/x%=40.31/52.5
(100/x)*x=(40.31/52.5)*x       - we multiply both sides of the equation by x
100=0.76780952380952*x       - we divide both sides of the equation by (0.76780952380952) to get x
100/0.76780952380952=x
130.24063507814=x
x=130.24063507814

now we have:
52.5 is 130.24063507814% of 40.31
