What is 20.8 percent of 13.52 - 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 13.52 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 13.52 is 100%, so we can write it down as 13.52=100%.
4. We know, that x is 20.8% of the output value, so we can write it down as x=20.8%.
5. Now we have two simple equations:
1) 13.52=100%
2) x=20.8%
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:
13.52/x=100%/20.8%
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 20.8% of 13.52

13.52/x=100/20.8
(13.52/x)*x=(100/20.8)*x       - we multiply both sides of the equation by x
13.52=4.8076923076923*x       - we divide both sides of the equation by (4.8076923076923) to get x
13.52/4.8076923076923=x
2.81216=x
x=2.81216

now we have:
20.8% of 13.52=2.81216
