Answer:

Additive inverse is #0.125# and multiplicative inverse is #-8#.

Explanation:

Additive inverse of a number #x# is the number, which when added to it gives #0# (the additive identity).

Hence additive inverse of #-0.125# is #0.125#.

Multipicative inverse of a number #x# is the number, which when multiplied by it gives #1# (the multiplicative identity).

Hence multiplicative inverse of #-0.125# is #1/(-0.125)=-1000/125=-8#.

Note : #0# is additive identity as when added to any number, it results in the same number. #1# is multiplicative identity as when multiplied with any number, it results in the same number.
