66.6 is what percent of 266 - 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 266 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 266, so we can write it down as 100%=266.
4. We know, that x% equals 66.6 of the output value, so we can write it down as x%=66.6.
5. Now we have two simple equations:
1) 100%=266
2) x%=66.6
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%=266/66.6
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 66.6 is what percent of 266

100%/x%=266/66.6
(100/x)*x=(266/66.6)*x       - we multiply both sides of the equation by x
100=3.993993993994*x       - we divide both sides of the equation by (3.993993993994) to get x
100/3.993993993994=x
25.037593984962=x
x=25.037593984962

now we have:
66.6 is 25.037593984962% of 266
