39.18 is what percent of 250.31 - 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 250.31 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 250.31, so we can write it down as 100%=250.31.
4. We know, that x% equals 39.18 of the output value, so we can write it down as x%=39.18.
5. Now we have two simple equations:
1) 100%=250.31
2) x%=39.18
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%=250.31/39.18
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 39.18 is what percent of 250.31

100%/x%=250.31/39.18
(100/x)*x=(250.31/39.18)*x       - we multiply both sides of the equation by x
100=6.388718734048*x       - we divide both sides of the equation by (6.388718734048) to get x
100/6.388718734048=x
15.652590787424=x
x=15.652590787424

now we have:
39.18 is 15.652590787424% of 250.31
