54.78 is what percent of 99.6 - 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 99.6 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 99.6, so we can write it down as 100%=99.6.
4. We know, that x% equals 54.78 of the output value, so we can write it down as x%=54.78.
5. Now we have two simple equations:
1) 100%=99.6
2) x%=54.78
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%=99.6/54.78
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 54.78 is what percent of 99.6

100%/x%=99.6/54.78
(100/x)*x=(99.6/54.78)*x       - we multiply both sides of the equation by x
100=1.8181818181818*x       - we divide both sides of the equation by (1.8181818181818) to get x
100/1.8181818181818=x
55=x
x=55

now we have:
54.78 is 55% of 99.6
