57 is what percent of 2216 - 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 2216 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 2216, so we can write it down as 100%=2216.
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%=2216
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%=2216/57
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 2216

100%/x%=2216/57
(100/x)*x=(2216/57)*x       - we multiply both sides of the equation by x
100=38.877192982456*x       - we divide both sides of the equation by (38.877192982456) to get x
100/38.877192982456=x
2.572202166065=x
x=2.572202166065

now we have:
57 is 2.572202166065% of 2216
