What is 6.66E-5 percent of 15000000 - 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 15000000 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 15000000 is 100%, so we can write it down as 15000000=100%.
4. We know, that x is 6.66E-5% of the output value, so we can write it down as x=6.66E-5%.
5. Now we have two simple equations:
1) 15000000=100%
2) x=6.66E-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:
15000000/x=100%/6.66E-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 6.66E-5% of 15000000

15000000/x=100/6.66E-5
(15000000/x)*x=(100/6.66E-5)*x       - we multiply both sides of the equation by x
15000000=1501501.5015015*x       - we divide both sides of the equation by (1501501.5015015) to get x
15000000/1501501.5015015=x
9.99=x
x=9.99

now we have:
6.66E-5% of 15000000=9.99
