What is 66.92 percent of 20 - 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 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 is 100%, so we can write it down as 20=100%.
4. We know, that x is 66.92% of the output value, so we can write it down as x=66.92%.
5. Now we have two simple equations:
1) 20=100%
2) x=66.92%
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/x=100%/66.92%
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 66.92% of 20

20/x=100/66.92
(20/x)*x=(100/66.92)*x       - we multiply both sides of the equation by x
20=1.4943215780036*x       - we divide both sides of the equation by (1.4943215780036) to get x
20/1.4943215780036=x
13.384=x
x=13.384

now we have:
66.92% of 20=13.384
