What is 20.52 percent of 42.5 - 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 42.5 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 42.5 is 100%, so we can write it down as 42.5=100%.
4. We know, that x is 20.52% of the output value, so we can write it down as x=20.52%.
5. Now we have two simple equations:
1) 42.5=100%
2) x=20.52%
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:
42.5/x=100%/20.52%
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for what is 20.52% of 42.5

42.5/x=100/20.52
(42.5/x)*x=(100/20.52)*x       - we multiply both sides of the equation by x
42.5=4.8732943469786*x       - we divide both sides of the equation by (4.8732943469786) to get x
42.5/4.8732943469786=x
8.721=x
x=8.721

now we have:
20.52% of 42.5=8.721
