What is 1.4E-5 percent of 31890000 - 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 31890000 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 31890000 is 100%, so we can write it down as 31890000=100%.
4. We know, that x is 1.4E-5% of the output value, so we can write it down as x=1.4E-5%.
5. Now we have two simple equations:
1) 31890000=100%
2) x=1.4E-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:
31890000/x=100%/1.4E-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 1.4E-5% of 31890000

31890000/x=100/1.4E-5
(31890000/x)*x=(100/1.4E-5)*x       - we multiply both sides of the equation by x
31890000=7142857.1428571*x       - we divide both sides of the equation by (7142857.1428571) to get x
31890000/7142857.1428571=x
4.4646=x
x=4.4646

now we have:
1.4E-5% of 31890000=4.4646
