54 is what percent of 447 - 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 447 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 447, so we can write it down as 100%=447.
4. We know, that x% equals 54 of the output value, so we can write it down as x%=54.
5. Now we have two simple equations:
1) 100%=447
2) x%=54
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%=447/54
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 54 is what percent of 447

100%/x%=447/54
(100/x)*x=(447/54)*x       - we multiply both sides of the equation by x
100=8.2777777777778*x       - we divide both sides of the equation by (8.2777777777778) to get x
100/8.2777777777778=x
12.080536912752=x
x=12.080536912752

now we have:
54 is 12.080536912752% of 447
