54.42 is what percent of 75 - 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 75 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 75, so we can write it down as 100%=75.
4. We know, that x% equals 54.42 of the output value, so we can write it down as x%=54.42.
5. Now we have two simple equations:
1) 100%=75
2) x%=54.42
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%=75/54.42
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 54.42 is what percent of 75

100%/x%=75/54.42
(100/x)*x=(75/54.42)*x       - we multiply both sides of the equation by x
100=1.3781697905182*x       - we divide both sides of the equation by (1.3781697905182) to get x
100/1.3781697905182=x
72.56=x
x=72.56

now we have:
54.42 is 72.56% of 75
