57 is what percent of 1536 - 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 1536 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 1536, so we can write it down as 100%=1536.
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%=1536
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%=1536/57
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 1536

100%/x%=1536/57
(100/x)*x=(1536/57)*x       - we multiply both sides of the equation by x
100=26.947368421053*x       - we divide both sides of the equation by (26.947368421053) to get x
100/26.947368421053=x
3.7109375=x
x=3.7109375

now we have:
57 is 3.7109375% of 1536
