57.6 is what percent of 288.4 - 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 288.4 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 288.4, so we can write it down as 100%=288.4.
4. We know, that x% equals 57.6 of the output value, so we can write it down as x%=57.6.
5. Now we have two simple equations:
1) 100%=288.4
2) x%=57.6
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%=288.4/57.6
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 57.6 is what percent of 288.4

100%/x%=288.4/57.6
(100/x)*x=(288.4/57.6)*x       - we multiply both sides of the equation by x
100=5.0069444444444*x       - we divide both sides of the equation by (5.0069444444444) to get x
100/5.0069444444444=x
19.97226074896=x
x=19.97226074896

now we have:
57.6 is 19.97226074896% of 288.4
