What is 7.1E-5 percent of 310000000 - 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 310000000 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 310000000 is 100%, so we can write it down as 310000000=100%.
4. We know, that x is 7.1E-5% of the output value, so we can write it down as x=7.1E-5%.
5. Now we have two simple equations:
1) 310000000=100%
2) x=7.1E-5%
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:
310000000/x=100%/7.1E-5%
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 7.1E-5% of 310000000

310000000/x=100/7.1E-5
(310000000/x)*x=(100/7.1E-5)*x       - we multiply both sides of the equation by x
310000000=1408450.7042254*x       - we divide both sides of the equation by (1408450.7042254) to get x
310000000/1408450.7042254=x
220.1=x
x=220.1

now we have:
7.1E-5% of 310000000=220.1
