39.2 is what percent of 140000000 - 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 140000000 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 140000000, so we can write it down as 100%=140000000.
4. We know, that x% equals 39.2 of the output value, so we can write it down as x%=39.2.
5. Now we have two simple equations:
1) 100%=140000000
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:
100%/x%=140000000/39.2
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 39.2 is what percent of 140000000

100%/x%=140000000/39.2
(100/x)*x=(140000000/39.2)*x       - we multiply both sides of the equation by x
100=3571428.5714286*x       - we divide both sides of the equation by (3571428.5714286) to get x
100/3571428.5714286=x
2.8E-5=x
x=2.8E-5

now we have:
39.2 is 2.8E-5% of 140000000
