57.31 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 57.31 of the output value, so we can write it down as x%=57.31.
5. Now we have two simple equations:
1) 100%=75
2) x%=57.31
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%=75/57.31
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 57.31 is what percent of 75

100%/x%=75/57.31
(100/x)*x=(75/57.31)*x       - we multiply both sides of the equation by x
100=1.308672134008*x       - we divide both sides of the equation by (1.308672134008) to get x
100/1.308672134008=x
76.413333333333=x
x=76.413333333333

now we have:
57.31 is 76.413333333333% of 75
