20.8 is what percent of 54.1 - 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 54.1 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 54.1, so we can write it down as 100%=54.1.
4. We know, that x% equals 20.8 of the output value, so we can write it down as x%=20.8.
5. Now we have two simple equations:
1) 100%=54.1
2) x%=20.8
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%=54.1/20.8
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 20.8 is what percent of 54.1

100%/x%=54.1/20.8
(100/x)*x=(54.1/20.8)*x       - we multiply both sides of the equation by x
100=2.6009615384615*x       - we divide both sides of the equation by (2.6009615384615) to get x
100/2.6009615384615=x
38.447319778189=x
x=38.447319778189

now we have:
20.8 is 38.447319778189% of 54.1
