123.5 is what percent of 161 - 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 161 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 161, so we can write it down as 100%=161.
4. We know, that x% equals 123.5 of the output value, so we can write it down as x%=123.5.
5. Now we have two simple equations:
1) 100%=161
2) x%=123.5
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%=161/123.5
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 123.5 is what percent of 161

100%/x%=161/123.5
(100/x)*x=(161/123.5)*x       - we multiply both sides of the equation by x
100=1.3036437246964*x       - we divide both sides of the equation by (1.3036437246964) to get x
100/1.3036437246964=x
76.708074534161=x
x=76.708074534161

now we have:
123.5 is 76.708074534161% of 161
