It does. For instance, to get the reciprocal of 4, enter the following sequence: 4 [1/x] (this last key to be found third row down, second black key in). The decimal 0.25 will appear as the result. Convert this, if you want, to the fraction 1/4 by pressing the yellow function key [2nd], then {F<>D] located bottom, far left. Hope that's what you wanted!

Hi I'm trying to find the reciprocal sign on my Casio fx-300es

If you mean "1-over-x" then it's the key marked "x-superscript-negative-one" just right and below the big round cursor pad. If you mean "reciprocal sign" more commonly referred to as "negative" or "change-sign" then it's the key marked "(-)" two keys above the "7" key.
