108.5 is what percent of 122 - 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 122 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 122, so we can write it down as 100%=122.
4. We know, that x% equals 108.5 of the output value, so we can write it down as x%=108.5.
5. Now we have two simple equations:
1) 100%=122
2) x%=108.5
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%=122/108.5
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 108.5 is what percent of 122

100%/x%=122/108.5
(100/x)*x=(122/108.5)*x       - we multiply both sides of the equation by x
100=1.1244239631336*x       - we divide both sides of the equation by (1.1244239631336) to get x
100/1.1244239631336=x
88.934426229508=x
x=88.934426229508

now we have:
108.5 is 88.934426229508% of 122
