39.06 is what percent of 31.51 - 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 31.51 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 31.51, so we can write it down as 100%=31.51.
4. We know, that x% equals 39.06 of the output value, so we can write it down as x%=39.06.
5. Now we have two simple equations:
1) 100%=31.51
2) x%=39.06
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%=31.51/39.06
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 39.06 is what percent of 31.51

100%/x%=31.51/39.06
(100/x)*x=(31.51/39.06)*x       - we multiply both sides of the equation by x
100=0.80670762928827*x       - we divide both sides of the equation by (0.80670762928827) to get x
100/0.80670762928827=x
123.96064741352=x
x=123.96064741352

now we have:
39.06 is 123.96064741352% of 31.51
