12.57 is what percent of 37 - 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 37 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 37, so we can write it down as 100%=37.
4. We know, that x% equals 12.57 of the output value, so we can write it down as x%=12.57.
5. Now we have two simple equations:
1) 100%=37
2) x%=12.57
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%=37/12.57
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 12.57 is what percent of 37

100%/x%=37/12.57
(100/x)*x=(37/12.57)*x       - we multiply both sides of the equation by x
100=2.9435163086714*x       - we divide both sides of the equation by (2.9435163086714) to get x
100/2.9435163086714=x
33.972972972973=x
x=33.972972972973

now we have:
12.57 is 33.972972972973% of 37
