What is 3937500 percent of 12.5 - 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 12.5 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 12.5 is 100%, so we can write it down as 12.5=100%.
4. We know, that x is 3937500% of the output value, so we can write it down as x=3937500%.
5. Now we have two simple equations:
1) 12.5=100%
2) x=3937500%
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:
12.5/x=100%/3937500%
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 3937500% of 12.5

12.5/x=100/3937500
(12.5/x)*x=(100/3937500)*x       - we multiply both sides of the equation by x
12.5=2.5396825396825E-5*x       - we divide both sides of the equation by (2.5396825396825E-5) to get x
12.5/2.5396825396825E-5=x
492187.5=x
x=492187.5

now we have:
3937500% of 12.5=492187.5
