139.25 is what percent of 240 - 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 240 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 240, so we can write it down as 100%=240.
4. We know, that x% equals 139.25 of the output value, so we can write it down as x%=139.25.
5. Now we have two simple equations:
1) 100%=240
2) x%=139.25
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%=240/139.25
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 139.25 is what percent of 240

100%/x%=240/139.25
(100/x)*x=(240/139.25)*x       - we multiply both sides of the equation by x
100=1.7235188509874*x       - we divide both sides of the equation by (1.7235188509874) to get x
100/1.7235188509874=x
58.020833333333=x
x=58.020833333333

now we have:
139.25 is 58.020833333333% of 240
