Hope this is the answer....

Answer 2

Definition of multiplicative inverse :

$\implies$ If a and b be two numbers such that ab = 1, then they are called multiplicative inverse of each other. Only 0 has no reciprocal number.

Answer :

Let, a be the multiplicative inverse of ( - 1 )

Then,

a × ( - 1 ) = 1

$\implies$ a × ( - 1 ) × ( - 1 ) = 1 × ( - 1 )

$\implies \bold{a = - 1}$

Hence, the required reciprocal of ( - 1 ) be ( - 1 ).
