The rational numbers are $\mathrm{de} n s e$, meaning that there are infinite rational numbers between any two given rational numbers
First observe that $\frac{1}{3} < \frac{7}{8}$. There are infinite rationals (fractions) between these two given numbers, for example, the mid point between the two $m$.
But $m = \frac{\frac{1}{3} + \frac{7}{8}}{2} = \frac{\frac{8}{24} + \frac{21}{24}}{2} = \frac{\frac{29}{24}}{2} = \frac{29}{48}$
