What is 2.1E-6 percent of 380000000 - 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 380000000 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 380000000 is 100%, so we can write it down as 380000000=100%.
4. We know, that x is 2.1E-6% of the output value, so we can write it down as x=2.1E-6%.
5. Now we have two simple equations:
1) 380000000=100%
2) x=2.1E-6%
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:
380000000/x=100%/2.1E-6%
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 2.1E-6% of 380000000

380000000/x=100/2.1E-6
(380000000/x)*x=(100/2.1E-6)*x       - we multiply both sides of the equation by x
380000000=47619047.619048*x       - we divide both sides of the equation by (47619047.619048) to get x
380000000/47619047.619048=x
7.98=x
x=7.98

now we have:
2.1E-6% of 380000000=7.98
