No, you have to use a substitution (s///) for that.  tr/// is for
character-to-character translations.

>$variable =~ tr/[\xBD]/"1/2"/;                 #tr doesn't like this, so I tried...

Fails because of the / in "1/2".  You'd have to backslash it, but that
doesn't make the tr/// do what you expect.  Leave out the [...] in the
left-hand side of the tr///, because a tr/// is already using character
classes.

>$replacement = "1/2";
>$variable =~ tr/[\xBD]/$replacement/;          #tr replaces \xBD with 'r', then I 
>tried

Fails because tr/// does not interpolate variables.

>$variable =~ tr/[\xBD]/\$replacement/; # just to see if the \ in front of 
>the $ would work.. It didn't

Fails as well.

You want:

  s{\xBD}{1/2}g;

Plain and simple:  "find hex character BD, and replace it with '1/2'".
