The multiplicative inverse of a negative number is just like any positive number, the sum of the products of negative numbers Its reciprocal must be equal to 1. Therefore, the multiplicative inverse of any negative number is its reciprocal. For example, (-6) × (-1/6) = 1, so the multiplicative inverse of -6 is -1/6.

Is the multiplicative inverse of a negative number positive?

A very important property of multiplicative inverses is that when a number is multiplied by its reciprocal or multiplicative inverse, we get 1. …so, the multiplicative inverse of a A negative number will just be a negative number. Therefore, our answer is option B) negative rational numbers.
