What is 2.0E-7 percent of 1000000000 - 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 1000000000 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 1000000000 is 100%, so we can write it down as 1000000000=100%.
4. We know, that x is 2.0E-7% of the output value, so we can write it down as x=2.0E-7%.
5. Now we have two simple equations:
1) 1000000000=100%
2) x=2.0E-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:
1000000000/x=100%/2.0E-7%
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 2.0E-7% of 1000000000

1000000000/x=100/2.0E-7
(1000000000/x)*x=(100/2.0E-7)*x       - we multiply both sides of the equation by x
1000000000=500000000*x       - we divide both sides of the equation by (500000000) to get x
1000000000/500000000=x
2=x
x=2

now we have:
2.0E-7% of 1000000000=2
