State True or False :

(i) There exists a rational number which is neither positive nor negative.

(ii) Every rational number has a multiplicative inverse.

(iii) Every rational number when expressed in its standard form has its denominator greater than the numerator.

(iv) The sum of a rational number and its additive inverse is always

(v) The product of a rational number and its multiplicative inverse is always

(vi) Any two equivalent rational numbers have the same standard form.

(vii) The product of any two rational numbers is also a rational number.

(viii) A rational number when divided by another rational number always gives a rational number.

(ix) Every rational number can be represented on a number line.

(x) The rational numbers smaller than a given rational number $\dfrac{p}{q}$ lie to the left of $\dfrac{p}{q}$.

Assertion: Two rational numbers with different numerators can never be equal.

Reason: A rational number $\dfrac{p}{q}$ is said to be in standard form if q is positive and p and q have no common factor other than 1.
