54.3 is what percent of 66 - 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 66 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 66, so we can write it down as 100%=66.
4. We know, that x% equals 54.3 of the output value, so we can write it down as x%=54.3.
5. Now we have two simple equations:
1) 100%=66
2) x%=54.3
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%=66/54.3
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 54.3 is what percent of 66

100%/x%=66/54.3
(100/x)*x=(66/54.3)*x       - we multiply both sides of the equation by x
100=1.2154696132597*x       - we divide both sides of the equation by (1.2154696132597) to get x
100/1.2154696132597=x
82.272727272727=x
x=82.272727272727

now we have:
54.3 is 82.272727272727% of 66
