Draw the number line and represent the rational number $\frac{7}{8}$ on it.

Draw the number line and represent the following rational number $\frac{-7}{4}$ on it.

Draw the number line and represent the rational number $\frac{-5}{8}$ on it.

The points $\mathrm{P}, \mathrm{Q}, \mathrm{R}, \mathrm{S}, \mathrm{T}, \mathrm{U}, \mathrm{A}$ and $\mathrm{B}$ on the number line are such that, $\mathrm{T}\mathrm{R}=\mathrm{R}\mathrm{S}=\mathrm{S}\mathrm{U}$ and $\mathrm{A}\mathrm{P}=\mathrm{P}\mathrm{Q}=\mathrm{Q}\mathrm{B}$. Name the rational numbers represented by $\mathrm{P}, \mathrm{Q}, \mathrm{R}$ and $S$.
