54.97 is what percent of 20 - 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 20 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 20, so we can write it down as 100%=20.
4. We know, that x% equals 54.97 of the output value, so we can write it down as x%=54.97.
5. Now we have two simple equations:
1) 100%=20
2) x%=54.97
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%=20/54.97
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 54.97 is what percent of 20

100%/x%=20/54.97
(100/x)*x=(20/54.97)*x       - we multiply both sides of the equation by x
100=0.36383481899218*x       - we divide both sides of the equation by (0.36383481899218) to get x
100/0.36383481899218=x
274.85=x
x=274.85

now we have:
54.97 is 274.85% of 20
