13.6 is what percent of 57 - 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 57 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 57, so we can write it down as 100%=57.
4. We know, that x% equals 13.6 of the output value, so we can write it down as x%=13.6.
5. Now we have two simple equations:
1) 100%=57
2) x%=13.6
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%=57/13.6
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 13.6 is what percent of 57

100%/x%=57/13.6
(100/x)*x=(57/13.6)*x       - we multiply both sides of the equation by x
100=4.1911764705882*x       - we divide both sides of the equation by (4.1911764705882) to get x
100/4.1911764705882=x
23.859649122807=x
x=23.859649122807

now we have:
13.6 is 23.859649122807% of 57
