2000000 is what percent of 9 - 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 9 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 100% equals 9, so we can write it down as 100%=9.
4. We know, that x% equals 2000000 of the output value, so we can write it down as x%=2000000.
5. Now we have two simple equations:
1) 100%=9
2) x%=2000000
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:
100%/x%=9/2000000
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 2000000 is what percent of 9

100%/x%=9/2000000
(100/x)*x=(9/2000000)*x       - we multiply both sides of the equation by x
100=4.5E-6*x       - we divide both sides of the equation by (4.5E-6) to get x
100/4.5E-6=x
22222222.222222=x
x=22222222.222222

now we have:
2000000 is 22222222.222222% of 9
