What is 11.85 percent of 21.9 - 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 21.9 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 21.9 is 100%, so we can write it down as 21.9=100%.
4. We know, that x is 11.85% of the output value, so we can write it down as x=11.85%.
5. Now we have two simple equations:
1) 21.9=100%
2) x=11.85%
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:
21.9/x=100%/11.85%
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 11.85% of 21.9

21.9/x=100/11.85
(21.9/x)*x=(100/11.85)*x       - we multiply both sides of the equation by x
21.9=8.4388185654008*x       - we divide both sides of the equation by (8.4388185654008) to get x
21.9/8.4388185654008=x
2.59515=x
x=2.59515

now we have:
11.85% of 21.9=2.59515
