Yes, another way to find a rational number between any two rational numbers is by taking their average. For two rational numbers $a$ and $b$, the average is calculated as $\frac{a+b}{2}$. This value is always a rational number that lies strictly between $a$ and $b$.

For example, a rational number between 1 and $\frac{3}{2}$ is found by taking their average: $\frac{1 + \frac{3}{2}}{2} = \frac{5}{4}$. Another effective method is to express the two rational numbers as equivalent fractions with a common, larger denominator, which allows us to easily identify multiple rational numbers lying between them.
