57 is what percent of 938 - 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 938 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 938, so we can write it down as 100%=938.
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%=938
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%=938/57
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 938

100%/x%=938/57
(100/x)*x=(938/57)*x       - we multiply both sides of the equation by x
100=16.456140350877*x       - we divide both sides of the equation by (16.456140350877) to get x
100/16.456140350877=x
6.0767590618337=x
x=6.0767590618337

now we have:
57 is 6.0767590618337% of 938
