Given:

The given value is
.

To find:

The multiplicative inverse of
.

Solution:

We know that
is the multiplicative interval of
if
xy=1 .

Let
be the multiplicative inverse of the given value
. Then,

(-a)* x=1

Divide both sides by
.

x=(1)/(-a)

x=-(1)/(a)

Therefore, the multiplicative inverse of
is
. Hence the correct option is A.
