57 is what percent of 2013 - 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 2013 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 2013, so we can write it down as 100%=2013.
4. We know, that x% equals 57 of the output value, so we can write it down as x%=57.
5. Now we have two simple equations:
1) 100%=2013
2) x%=57
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%=2013/57
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 57 is what percent of 2013

100%/x%=2013/57
(100/x)*x=(2013/57)*x       - we multiply both sides of the equation by x
100=35.315789473684*x       - we divide both sides of the equation by (35.315789473684) to get x
100/35.315789473684=x
2.8315946348733=x
x=2.8315946348733

now we have:
57 is 2.8315946348733% of 2013
