What is 13.65 percent of 20.8 - 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 20.8 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 20.8 is 100%, so we can write it down as 20.8=100%.
4. We know, that x is 13.65% of the output value, so we can write it down as x=13.65%.
5. Now we have two simple equations:
1) 20.8=100%
2) x=13.65%
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:
20.8/x=100%/13.65%
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 13.65% of 20.8

20.8/x=100/13.65
(20.8/x)*x=(100/13.65)*x       - we multiply both sides of the equation by x
20.8=7.3260073260073*x       - we divide both sides of the equation by (7.3260073260073) to get x
20.8/7.3260073260073=x
2.8392=x
x=2.8392

now we have:
13.65% of 20.8=2.8392
