8.52 is what percent of 20.28 - 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 20.28 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 20.28, so we can write it down as 100%=20.28.
4. We know, that x% equals 8.52 of the output value, so we can write it down as x%=8.52.
5. Now we have two simple equations:
1) 100%=20.28
2) x%=8.52
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%=20.28/8.52
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 8.52 is what percent of 20.28

100%/x%=20.28/8.52
(100/x)*x=(20.28/8.52)*x       - we multiply both sides of the equation by x
100=2.3802816901408*x       - we divide both sides of the equation by (2.3802816901408) to get x
100/2.3802816901408=x
42.011834319527=x
x=42.011834319527

now we have:
8.52 is 42.011834319527% of 20.28
