What is 3.0E-6 percent of 1300000000 - 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 1300000000 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 1300000000 is 100%, so we can write it down as 1300000000=100%.
4. We know, that x is 3.0E-6% of the output value, so we can write it down as x=3.0E-6%.
5. Now we have two simple equations:
1) 1300000000=100%
2) x=3.0E-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:
1300000000/x=100%/3.0E-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 3.0E-6% of 1300000000

1300000000/x=100/3.0E-6
(1300000000/x)*x=(100/3.0E-6)*x       - we multiply both sides of the equation by x
1300000000=33333333.333333*x       - we divide both sides of the equation by (33333333.333333) to get x
1300000000/33333333.333333=x
39=x
x=39

now we have:
3.0E-6% of 1300000000=39
