What is 39.2 percent of 39.2 - 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 39.2 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 39.2 is 100%, so we can write it down as 39.2=100%.
4. We know, that x is 39.2% of the output value, so we can write it down as x=39.2%.
5. Now we have two simple equations:
1) 39.2=100%
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:
39.2/x=100%/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 what is 39.2% of 39.2

39.2/x=100/39.2
(39.2/x)*x=(100/39.2)*x       - we multiply both sides of the equation by x
39.2=2.5510204081633*x       - we divide both sides of the equation by (2.5510204081633) to get x
39.2/2.5510204081633=x
15.3664=x
x=15.3664

now we have:
39.2% of 39.2=15.3664
