57.5 is what percent of 69.58 - 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 69.58 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 69.58, so we can write it down as 100%=69.58.
4. We know, that x% equals 57.5 of the output value, so we can write it down as x%=57.5.
5. Now we have two simple equations:
1) 100%=69.58
2) x%=57.5
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%=69.58/57.5
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 57.5 is what percent of 69.58

100%/x%=69.58/57.5
(100/x)*x=(69.58/57.5)*x       - we multiply both sides of the equation by x
100=1.2100869565217*x       - we divide both sides of the equation by (1.2100869565217) to get x
100/1.2100869565217=x
82.638689278528=x
x=82.638689278528

now we have:
57.5 is 82.638689278528% of 69.58
