666666 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 666666 of the output value, so we can write it down as x%=666666.
5. Now we have two simple equations:
1) 100%=9
2) x%=666666
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%=9/666666
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 666666 is what percent of 9

100%/x%=9/666666
(100/x)*x=(9/666666)*x       - we multiply both sides of the equation by x
100=1.3500013500013E-5*x       - we divide both sides of the equation by (1.3500013500013E-5) to get x
100/1.3500013500013E-5=x
7407400=x
x=7407400

now we have:
666666 is 7407400% of 9
