What is 20 percent of 11.685 - 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 11.685 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 11.685 is 100%, so we can write it down as 11.685=100%.
4. We know, that x is 20% of the output value, so we can write it down as x=20%.
5. Now we have two simple equations:
1) 11.685=100%
2) x=20%
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:
11.685/x=100%/20%
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% of 11.685

11.685/x=100/20
(11.685/x)*x=(100/20)*x       - we multiply both sides of the equation by x
11.685=5*x       - we divide both sides of the equation by (5) to get x
11.685/5=x
2.337=x
x=2.337

now we have:
20% of 11.685=2.337
