57.8 is what percent of 144 - 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 144 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 144, so we can write it down as 100%=144.
4. We know, that x% equals 57.8 of the output value, so we can write it down as x%=57.8.
5. Now we have two simple equations:
1) 100%=144
2) x%=57.8
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%=144/57.8
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 57.8 is what percent of 144

100%/x%=144/57.8
(100/x)*x=(144/57.8)*x       - we multiply both sides of the equation by x
100=2.4913494809689*x       - we divide both sides of the equation by (2.4913494809689) to get x
100/2.4913494809689=x
40.138888888889=x
x=40.138888888889

now we have:
57.8 is 40.138888888889% of 144
