555 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 555 of the output value, so we can write it down as x%=555.
5. Now we have two simple equations:
1) 100%=9
2) x%=555
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%=9/555
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 555 is what percent of 9

100%/x%=9/555
(100/x)*x=(9/555)*x       - we multiply both sides of the equation by x
100=0.016216216216216*x       - we divide both sides of the equation by (0.016216216216216) to get x
100/0.016216216216216=x
6166.6666666667=x
x=6166.6666666667

now we have:
555 is 6166.6666666667% of 9
