⇒Thereciprocalof 1=11=1⇒Thereciprocalof-1=1-1=-1Therefore, the numbers '1‘ and ’-1' are their own reciprocals.

$\Rightarrow$ $The reciprocal of$ $1 = \frac{1}{1} = 1$
$\Rightarrow$ $The reciprocal of - 1 = \frac{1}{- 1} = - 1$
Therefore, the numbers ' $1$ ‘ and ’ $- 1$ ' are their own reciprocals.
