What is 21.99 percent of 8.25 - 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 8.25 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 8.25 is 100%, so we can write it down as 8.25=100%.
4. We know, that x is 21.99% of the output value, so we can write it down as x=21.99%.
5. Now we have two simple equations:
1) 8.25=100%
2) x=21.99%
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:
8.25/x=100%/21.99%
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 21.99% of 8.25

8.25/x=100/21.99
(8.25/x)*x=(100/21.99)*x       - we multiply both sides of the equation by x
8.25=4.5475216007276*x       - we divide both sides of the equation by (4.5475216007276) to get x
8.25/4.5475216007276=x
1.814175=x
x=1.814175

now we have:
21.99% of 8.25=1.814175
