# Write: (i) The rational number that does not have a reciprocal.

(ii) The rational numbers that are equal to their reciprocals.

(iii) The rational number that is equal to its negative.

**Solution:**

(i) **Rational number does not have a reciprocal**

0(zero) is the rational number that does not have a reciprocal as it is undefined (∞).

0/0 = undefined

(ii) **The rational number that are equal to its reciprocals**

The rational numbers 1 and -1 are equal to their respective reciprocals.

Reciprocal of 1 is 1/1 = 1, Reciprocal of -1 is 1/(-1) = -1

(iii) **The rational number that is equal to its negative**

Rational number 0 is equal to its negative.

0 is neither a positive nor a negative number. Hence 0 is the same as -0.
