What is 0.0001 percent of 9000000 - 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 9000000 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 9000000 is 100%, so we can write it down as 9000000=100%.
4. We know, that x is 0.0001% of the output value, so we can write it down as x=0.0001%.
5. Now we have two simple equations:
1) 9000000=100%
2) x=0.0001%
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:
9000000/x=100%/0.0001%
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 0.0001% of 9000000

9000000/x=100/0.0001
(9000000/x)*x=(100/0.0001)*x       - we multiply both sides of the equation by x
9000000=1000000*x       - we divide both sides of the equation by (1000000) to get x
9000000/1000000=x
9=x
x=9

now we have:
0.0001% of 9000000=9
