92 is what percent of 685 - 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 685 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 685, so we can write it down as 100%=685.
4. We know, that x% equals 92 of the output value, so we can write it down as x%=92.
5. Now we have two simple equations:
1) 100%=685
2) x%=92
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%=685/92
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 92 is what percent of 685

100%/x%=685/92
(100/x)*x=(685/92)*x       - we multiply both sides of the equation by x
100=7.445652173913*x       - we divide both sides of the equation by (7.445652173913) to get x
100/7.445652173913=x
13.430656934307=x
x=13.430656934307

now we have:
92 is 13.430656934307% of 685
