Question
Compare: $\frac{-5}{8}$ and $\frac{7}{-12}$
✓
Answer
$\begin{aligned} & \frac{-5}{8} \text { and } \frac{7}{-12} \\ & \frac{-5}{8} \times 24, \frac{7}{-12} \times 24 \\ & \left(\therefore \frac{\mathrm{a}}{\mathrm{b}} \text { and } \frac{\mathrm{c}}{\mathrm{d}} \Rightarrow \mathrm{a} \times \mathrm{d} \text { and } \mathrm{b} \times \mathrm{c}\right) \\ & -15,-14 \\ & 15>14(\because \mathrm{a} \times \mathrm{d}>\mathrm{b} \times \mathrm{c}) \\ & \therefore \frac{-5}{8}>\frac{7}{-12}\end{aligned}$
