7.67 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 7.67 of the output value, so we can write it down as x%=7.67.
5. Now we have two simple equations:
1) 100%=9
2) x%=7.67
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%=9/7.67
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 7.67 is what percent of 9

100%/x%=9/7.67
(100/x)*x=(9/7.67)*x       - we multiply both sides of the equation by x
100=1.1734028683181*x       - we divide both sides of the equation by (1.1734028683181) to get x
100/1.1734028683181=x
85.222222222222=x
x=85.222222222222

now we have:
7.67 is 85.222222222222% of 9
