Answer 1

Concept of Rational Numbers:

A rational number is a number that can be expressed as the fraction $\frac{p}{q}$of two integers where $p,q$ are coprime and $q\ne 0$.

Putting different values for the numerator and denominator terms in the fraction will give different different rational numbers.

So, in between two rational numbers there will exists infinitely many rational numbers.

Hence, in between two rational number there is/are infinitely many rational numbers.
