Question

How do you find the additive and multiplicative inverse of -0.125?

Answer 1

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.
