9 is what percent of 6647 - 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 6647 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 6647, so we can write it down as 100%=6647.
4. We know, that x% equals 9 of the output value, so we can write it down as x%=9.
5. Now we have two simple equations:
1) 100%=6647
2) x%=9
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%=6647/9
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 9 is what percent of 6647

100%/x%=6647/9
(100/x)*x=(6647/9)*x       - we multiply both sides of the equation by x
100=738.55555555556*x       - we divide both sides of the equation by (738.55555555556) to get x
100/738.55555555556=x
0.13539942831352=x
x=0.13539942831352

now we have:
9 is 0.13539942831352% of 6647
