56 is what percent of 139 - 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 139 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 139, so we can write it down as 100%=139.
4. We know, that x% equals 56 of the output value, so we can write it down as x%=56.
5. Now we have two simple equations:
1) 100%=139
2) x%=56
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%=139/56
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 56 is what percent of 139

100%/x%=139/56
(100/x)*x=(139/56)*x       - we multiply both sides of the equation by x
100=2.4821428571429*x       - we divide both sides of the equation by (2.4821428571429) to get x
100/2.4821428571429=x
40.287769784173=x
x=40.287769784173

now we have:
56 is 40.287769784173% of 139
