    What you usually do is find the first two numbers after the decimal.

    .6666666...
    So it starts of as,
    66\%
    But then the other part is,
    .6666666...=\frac{2}{3}
    Thus you attach that to your precent to get,
    \boxed{ 66 \frac{2}{3} \%}

    Is it always best to convert from fraction notation to percent notation by first finding decicimal notation? Why or why not?

    Yes, how else would you do it?

    If you can change the denominator to 100 then you can skip decimal notation. But that's the only time...
