See a solution process below:

The additive inverse (let's call it $a$ ) is the number added to $8$ in this problem which will equal $0$ . Or,

$8 + a = 0$

$a = -8$

The additive inverse of $8$ is: $-8$

The multiplicative inverse (let's call it $m$ ) is the number multiplied to $8$ in this problem which will equal $1$ . Or,

$8 xx m = 0$

$m = 1/8$

The multiplicative inverse of $8$ is: $1/8$
