What is 66.666666667 percent of 12 - 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 12 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 12 is 100%, so we can write it down as 12=100%.
4. We know, that x is 66.666666667% of the output value, so we can write it down as x=66.666666667%.
5. Now we have two simple equations:
1) 12=100%
2) x=66.666666667%
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:
12/x=100%/66.666666667%
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 66.666666667% of 12

12/x=100/66.666666667
(12/x)*x=(100/66.666666667)*x       - we multiply both sides of the equation by x
12=1.4999999999925*x       - we divide both sides of the equation by (1.4999999999925) to get x
12/1.4999999999925=x
8.00000000004=x
x=8.00000000004

now we have:
66.666666667% of 12=8.00000000004
