54 is what percent of 249.42 - 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 249.42 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 249.42, so we can write it down as 100%=249.42.
4. We know, that x% equals 54 of the output value, so we can write it down as x%=54.
5. Now we have two simple equations:
1) 100%=249.42
2) x%=54
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%=249.42/54
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 54 is what percent of 249.42

100%/x%=249.42/54
(100/x)*x=(249.42/54)*x       - we multiply both sides of the equation by x
100=4.6188888888889*x       - we divide both sides of the equation by (4.6188888888889) to get x
100/4.6188888888889=x
21.65022853019=x
x=21.65022853019

now we have:
54 is 21.65022853019% of 249.42
