0.66 is what percent of 0.6666667 - 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 0.6666667 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 100% equals 0.6666667, so we can write it down as 100%=0.6666667.
4. We know, that x% equals 0.66 of the output value, so we can write it down as x%=0.66.
5. Now we have two simple equations:
1) 100%=0.6666667
2) x%=0.66
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:
100%/x%=0.6666667/0.66
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 0.66 is what percent of 0.6666667

100%/x%=0.6666667/0.66
(100/x)*x=(0.6666667/0.66)*x       - we multiply both sides of the equation by x
100=1.0101010606061*x       - we divide both sides of the equation by (1.0101010606061) to get x
100/1.0101010606061=x
98.99999505=x
x=98.99999505

now we have:
0.66 is 98.99999505% of 0.6666667
