What is 9.0E-5 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 350000000 is 100%, so we can write it down as 350000000=100%.
4. We know, that x is 9.0E-5% of the output value, so we can write it down as x=9.0E-5%.
5. Now we have two simple equations:
1) 350000000=100%
2) x=9.0E-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:
350000000/x=100%/9.0E-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 9.0E-5% of 350000000

350000000/x=100/9.0E-5
(350000000/x)*x=(100/9.0E-5)*x       - we multiply both sides of the equation by x
350000000=1111111.1111111*x       - we divide both sides of the equation by (1111111.1111111) to get x
350000000/1111111.1111111=x
315=x
x=315

now we have:
9.0E-5% of 350000000=315
