# Multiplicative inverse of a negative rational number is

(a) a positive rational number

(b) a negative rational number

(c) 0

(d) 1

**Solution:**

Multiplicative inverse of a rational number is which when multiplied with a rational number gives result 1.

So, if given number is negative rational

Then the other number would also be negative but reciprocal of it

Henceforth, it gives 1

Given: a rational number of the form -p/q

Its reciprocal is obtained just by flipping the numerator and the denominator with no change in the signs. Reciprocal = -q/p, which is a negative rational number.

**✦ Try This:** Multiplicative inverse of -1/4 is

Let it be x

(-1/4) × x = 1

x = -4/1

Hence, the multiplicative inverse is -4.
