39.7 is what percent of 100000 - 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 100000 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 100000, so we can write it down as 100%=100000.
4. We know, that x% equals 39.7 of the output value, so we can write it down as x%=39.7.
5. Now we have two simple equations:
1) 100%=100000
2) x%=39.7
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%=100000/39.7
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 39.7 is what percent of 100000

100%/x%=100000/39.7
(100/x)*x=(100000/39.7)*x       - we multiply both sides of the equation by x
100=2518.8916876574*x       - we divide both sides of the equation by (2518.8916876574) to get x
100/2518.8916876574=x
0.0397=x
x=0.0397

now we have:
39.7 is 0.0397% of 100000
