9.0E-6 is what percent of 350000000 - 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 350000000 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 100% equals 350000000, so we can write it down as 100%=350000000.
4. We know, that x% equals 9.0E-6 of the output value, so we can write it down as x%=9.0E-6.
5. Now we have two simple equations:
1) 100%=350000000
2) x%=9.0E-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:
100%/x%=350000000/9.0E-6
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 9.0E-6 is what percent of 350000000

100%/x%=350000000/9.0E-6
(100/x)*x=(350000000/9.0E-6)*x       - we multiply both sides of the equation by x
100=38888888888889*x       - we divide both sides of the equation by (38888888888889) to get x
100/38888888888889=x
2.5714285714286E-12=x
x=2.5714285714286E-12

now we have:
9.0E-6 is 2.5714285714286E-12% of 350000000
