54.04 is what percent of 21.5 - 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 21.5 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 21.5, so we can write it down as 100%=21.5.
4. We know, that x% equals 54.04 of the output value, so we can write it down as x%=54.04.
5. Now we have two simple equations:
1) 100%=21.5
2) x%=54.04
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%=21.5/54.04
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 54.04 is what percent of 21.5

100%/x%=21.5/54.04
(100/x)*x=(21.5/54.04)*x       - we multiply both sides of the equation by x
100=0.39785344189489*x       - we divide both sides of the equation by (0.39785344189489) to get x
100/0.39785344189489=x
251.3488372093=x
x=251.3488372093

now we have:
54.04 is 251.3488372093% of 21.5
