54.48 is what percent of 72.64 - 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 72.64 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 72.64, so we can write it down as 100%=72.64.
4. We know, that x% equals 54.48 of the output value, so we can write it down as x%=54.48.
5. Now we have two simple equations:
1) 100%=72.64
2) x%=54.48
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%=72.64/54.48
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 54.48 is what percent of 72.64

100%/x%=72.64/54.48
(100/x)*x=(72.64/54.48)*x       - we multiply both sides of the equation by x
100=1.3333333333333*x       - we divide both sides of the equation by (1.3333333333333) to get x
100/1.3333333333333=x
75=x
x=75

now we have:
54.48 is 75% of 72.64
