Answer 1

See a solution below:

Explanation:

The multiplicative inverse is when you multiply a number by its "Multiplicative Inverse" you get 1.

Or, if the number is `n` then the "Multiplicative Inverse" is `1/n`

The "Multiplicative Inverse" of `-7` is therefore: `1/-7` or `-1/7`

`-7 xx -1/7 = 1`
