52.5 is what percent of 20.57 - 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 20.57 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 20.57, so we can write it down as 100%=20.57.
4. We know, that x% equals 52.5 of the output value, so we can write it down as x%=52.5.
5. Now we have two simple equations:
1) 100%=20.57
2) x%=52.5
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%=20.57/52.5
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 52.5 is what percent of 20.57

100%/x%=20.57/52.5
(100/x)*x=(20.57/52.5)*x       - we multiply both sides of the equation by x
100=0.39180952380952*x       - we divide both sides of the equation by (0.39180952380952) to get x
100/0.39180952380952=x
255.22605736509=x
x=255.22605736509

now we have:
52.5 is 255.22605736509% of 20.57
