Plz help me out in number 9

Dear Student.

$$\begin{gathered} \mathrm{We} \mathrm{have}, \frac{-1}{2} \mathrm{and} \frac{5}{4} \\ \mathrm{Multiplying} \mathrm{numerator} \mathrm{and} \mathrm{denominator} \mathrm{of} \frac{-1}{2} \mathrm{with} 2, \mathrm{we} \mathrm{get} \frac{-2}{4} \\ \mathrm{Now} \mathrm{we} \mathrm{have} \mathrm{to} \mathrm{find} \mathrm{six} \mathrm{rational} \mathrm{numbers} \mathrm{between} \frac{-2}{4} \mathrm{and} \frac{5}{4} \\ \mathrm{So}, \mathrm{the} \mathrm{numbers} \mathrm{are}:\hspace{0.17em}\frac{-1}{4}, \frac{0}{4}, \frac{1}{4}, \frac{2}{4}, \frac{3}{4}, \frac{4}{4} \\ \mathrm{Simplifying} \mathrm{them}, \mathrm{we} \mathrm{get}: \\ \frac{-1}{4}, 0, \frac{1}{4}, \frac{1}{2}, \frac{3}{4}, 1 \end{gathered}$$

We hope that this answer solves your query.
