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.

(i) If we try to find the reciprocal of $${0}$$ then, we get an undefined quantity.

As, $$\frac{{1}}{{0}}=$$Not a number

So, we can say that $${0}$$ does not have a reciprocal.

(ii)Only numbers that are equal to their reciprocals are $${1}$$ and $$-{1}$$.

As, $$\frac{{1}}{{1}}={1}$$ and $$\frac{{1}}{{-{{1}}}}=-{1}$$

(iii)The rational number that is equal to its negative is $${0}$$.

As, $$-{\left({0}\right)}={0}$$
