What is 28.28 percent of 21.21 - 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 21.21 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 21.21 is 100%, so we can write it down as 21.21=100%.
4. We know, that x is 28.28% of the output value, so we can write it down as x=28.28%.
5. Now we have two simple equations:
1) 21.21=100%
2) x=28.28%
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:
21.21/x=100%/28.28%
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 28.28% of 21.21

21.21/x=100/28.28
(21.21/x)*x=(100/28.28)*x       - we multiply both sides of the equation by x
21.21=3.5360678925035*x       - we divide both sides of the equation by (3.5360678925035) to get x
21.21/3.5360678925035=x
5.998188=x
x=5.998188

now we have:
28.28% of 21.21=5.998188
