54.77 is what percent of 85.8 - 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 85.8 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 85.8, so we can write it down as 100%=85.8.
4. We know, that x% equals 54.77 of the output value, so we can write it down as x%=54.77.
5. Now we have two simple equations:
1) 100%=85.8
2) x%=54.77
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%=85.8/54.77
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 54.77 is what percent of 85.8

100%/x%=85.8/54.77
(100/x)*x=(85.8/54.77)*x       - we multiply both sides of the equation by x
100=1.5665510315866*x       - we divide both sides of the equation by (1.5665510315866) to get x
100/1.5665510315866=x
63.834498834499=x
x=63.834498834499

now we have:
54.77 is 63.834498834499% of 85.8
