Entering symbols by numbers is not a good idea since TeX does not use
latin1 encoding for its output, but its own formats (OT1/T1).

If you enter directly the symbol ½ (in text mode) you will indeed get
\frac{1}{2}, from what latin1.def says:
\ProvideTextCommandDefault{\textonehalf}{\ensuremath{\frac12}}
It seems that the command \sfrac from the ltugboat.cls documentclass
does what you want:
\DeclareRobustCommand\sfrac[1]{\@ifnextchar/{\@sfrac{#1}}%
{\@sfrac{#1}/}}
\def\@sfrac#1/#2{\leavevmode\kern.1em\raise.5ex
\hbox{$\m@th\mbox{\fontsize\sf@size\z@
\selectfont#1}$}\kern-.1em
/\kern-.15em\lower.25ex
\hbox{$\m@th\mbox{\fontsize\sf@size\z@
\selectfont#2}$}}
Add the code in your preamble. It seems to me that you can use it as
\sfrac12 or \sfrac1/2, but I did not test it.
