57 is what percent of 22890 - 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 22890 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 22890, so we can write it down as 100%=22890.
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%=22890
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%=22890/57
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 22890

100%/x%=22890/57
(100/x)*x=(22890/57)*x       - we multiply both sides of the equation by x
100=401.57894736842*x       - we divide both sides of the equation by (401.57894736842) to get x
100/401.57894736842=x
0.24901703800786=x
x=0.24901703800786

now we have:
57 is 0.24901703800786% of 22890
