Additive inverse: $+4 3/5$

Multiplicative inverse (reciprocal) $-5/23$

Additive inverses add up to zero.
This means that the numbers are the same, but they have opposite signs.

$(-3) + (+3) =0" or "(+x) + (-x)=0$

So in this case, the additive inverse of $-4 3/5 " is " +4 3/5$

The multiplicative inverse is also known as the reciprocal.

Multiplicative inverses multiply to give $1$

$2/3 xx 3/2 = 1" or "a/b xx b/a =1$

In this case:

$-4 3/5 = -23/5" "larr$ write as an improper fraction

$-23/5 xx -5/23 = 1$
