What is 0.000666 percent of 3000000000 - 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 3000000000 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 3000000000 is 100%, so we can write it down as 3000000000=100%.
4. We know, that x is 0.000666% of the output value, so we can write it down as x=0.000666%.
5. Now we have two simple equations:
1) 3000000000=100%
2) x=0.000666%
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:
3000000000/x=100%/0.000666%
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 0.000666% of 3000000000

3000000000/x=100/0.000666
(3000000000/x)*x=(100/0.000666)*x       - we multiply both sides of the equation by x
3000000000=150150.15015015*x       - we divide both sides of the equation by (150150.15015015) to get x
3000000000/150150.15015015=x
19980=x
x=19980

now we have:
0.000666% of 3000000000=19980
