135.5 is what percent of 261 - 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 261 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 261, so we can write it down as 100%=261.
4. We know, that x% equals 135.5 of the output value, so we can write it down as x%=135.5.
5. Now we have two simple equations:
1) 100%=261
2) x%=135.5
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%=261/135.5
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 135.5 is what percent of 261

100%/x%=261/135.5
(100/x)*x=(261/135.5)*x       - we multiply both sides of the equation by x
100=1.9261992619926*x       - we divide both sides of the equation by (1.9261992619926) to get x
100/1.9261992619926=x
51.915708812261=x
x=51.915708812261

now we have:
135.5 is 51.915708812261% of 261
