What is 3.0E-7 percent of 323 - 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 323 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 323 is 100%, so we can write it down as 323=100%.
4. We know, that x is 3.0E-7% of the output value, so we can write it down as x=3.0E-7%.
5. Now we have two simple equations:
1) 323=100%
2) x=3.0E-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:
323/x=100%/3.0E-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 3.0E-7% of 323

323/x=100/3.0E-7
(323/x)*x=(100/3.0E-7)*x       - we multiply both sides of the equation by x
323=333333333.33333*x       - we divide both sides of the equation by (333333333.33333) to get x
323/333333333.33333=x
9.69E-7=x
x=9.69E-7

now we have:
3.0E-7% of 323=9.69E-7
