This is so basic, I'm kind of embarrassed, but I'm trying to add fractions on a number line and it looks like crap. Is there a way to drop fractions to a different level or something. I tried [below left]but that didn't look right either. Looking for something like [below below] to double up the drop, but I couldn't find an answer anywhere.

foreach x in {-1,...,5} % the numbers

node [below] at (x,-0.1) {$x$};

node [above] at (1.67,0.5) {A};

node [below] at (1.67,-0) {1$frac{2}{3}$};

end{tikzpicture}

Towards an answer ... don't know precisely what you want... positioning allows, as its name suggest, for an intuitive positioning. It also helps to work with the anchor=base key in this case, I'd say.
