57 is what percent of 249 - 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 249 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 249, so we can write it down as 100%=249.
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%=249
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%=249/57
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 249

100%/x%=249/57
(100/x)*x=(249/57)*x       - we multiply both sides of the equation by x
100=4.3684210526316*x       - we divide both sides of the equation by (4.3684210526316) to get x
100/4.3684210526316=x
22.89156626506=x
x=22.89156626506

now we have:
57 is 22.89156626506% of 249
