Additive inverse is $+0.5$

Multiplicative inverse is $-2$

ADDITIVE inverses add to make $0$ .
They have the same number, but opposite signs:

For example: $(-3) + (+3) = 0$

In this case $(-0.5) + (+0.5) = 0$

The MULTIPLICATIVE inverse is the same as the RECIPROCAL.

The product of a number and its multiplicative inverse is $1$

$2/3 xx 3/2 = 1$

In this case $-0.5 = -1/2$

$-1/2 xx-2/1 = 1$
