52.8 is what percent of 249.1 - 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 249.1 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 249.1, so we can write it down as 100%=249.1.
4. We know, that x% equals 52.8 of the output value, so we can write it down as x%=52.8.
5. Now we have two simple equations:
1) 100%=249.1
2) x%=52.8
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%=249.1/52.8
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 52.8 is what percent of 249.1

100%/x%=249.1/52.8
(100/x)*x=(249.1/52.8)*x       - we multiply both sides of the equation by x
100=4.717803030303*x       - we divide both sides of the equation by (4.717803030303) to get x
100/4.717803030303=x
21.196306704135=x
x=21.196306704135

now we have:
52.8 is 21.196306704135% of 249.1
