137.97 is what percent of 255 - 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 255 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 255, so we can write it down as 100%=255.
4. We know, that x% equals 137.97 of the output value, so we can write it down as x%=137.97.
5. Now we have two simple equations:
1) 100%=255
2) x%=137.97
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%=255/137.97
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 137.97 is what percent of 255

100%/x%=255/137.97
(100/x)*x=(255/137.97)*x       - we multiply both sides of the equation by x
100=1.8482278756251*x       - we divide both sides of the equation by (1.8482278756251) to get x
100/1.8482278756251=x
54.105882352941=x
x=54.105882352941

now we have:
137.97 is 54.105882352941% of 255
