8.5 is what percent of 108 - 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 108 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 108, so we can write it down as 100%=108.
4. We know, that x% equals 8.5 of the output value, so we can write it down as x%=8.5.
5. Now we have two simple equations:
1) 100%=108
2) x%=8.5
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%=108/8.5
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 8.5 is what percent of 108

100%/x%=108/8.5
(100/x)*x=(108/8.5)*x       - we multiply both sides of the equation by x
100=12.705882352941*x       - we divide both sides of the equation by (12.705882352941) to get x
100/12.705882352941=x
7.8703703703704=x
x=7.8703703703704

now we have:
8.5 is 7.8703703703704% of 108
