In order to find the reciprocal of a number, we should just flop it over, like so:-

$\sf{The~reciprocal~of~a~is~(1)/(a)}$

Flop it over:-

$\sf{-\displaystyle(1)/(1) }$

There's something you should notice about this number.

No matter how we flop it over, we're going to end up with -1.

Hence, the reciprocal of -1 is:-

$\boxed{-1}$

Hope everything is clear; if you need any clarification/explanation, kindly let me know, and I'll comment and/or edit my answer :)
