66 is what percent of 1011 - 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 1011 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 1011, so we can write it down as 100%=1011.
4. We know, that x% equals 66 of the output value, so we can write it down as x%=66.
5. Now we have two simple equations:
1) 100%=1011
2) x%=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%=1011/66
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 66 is what percent of 1011

100%/x%=1011/66
(100/x)*x=(1011/66)*x       - we multiply both sides of the equation by x
100=15.318181818182*x       - we divide both sides of the equation by (15.318181818182) to get x
100/15.318181818182=x
6.5281899109792=x
x=6.5281899109792

now we have:
66 is 6.5281899109792% of 1011
