What is 66.66 percent of 8.16 - 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 8.16 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 8.16 is 100%, so we can write it down as 8.16=100%.
4. We know, that x is 66.66% of the output value, so we can write it down as x=66.66%.
5. Now we have two simple equations:
1) 8.16=100%
2) x=66.66%
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:
8.16/x=100%/66.66%
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 66.66% of 8.16

8.16/x=100/66.66
(8.16/x)*x=(100/66.66)*x       - we multiply both sides of the equation by x
8.16=1.5001500150015*x       - we divide both sides of the equation by (1.5001500150015) to get x
8.16/1.5001500150015=x
5.439456=x
x=5.439456

now we have:
66.66% of 8.16=5.439456
