Arrange the following in descending order -3/8 ,-7/12, -1/4

Answer 1

Dear Student,


$$\begin{gathered} \frac{-3}{8},\frac{-7}{12},\frac{-1}{4} \\ \mathrm{LCM}\mathrm{of}\mathrm{denominators}=\mathrm{LCM}\left(8,12,4\right)=24 \\ \frac{{\displaystyle -3}}{{\displaystyle 8}}\times \frac{3}{3},\frac{{\displaystyle -7}}{{\displaystyle 12}}\times \frac{2}{2},\frac{{\displaystyle -1}}{{\displaystyle 4}}\times \frac{6}{6} \\ \frac{-9}{24},\frac{-14}{24},\frac{-6}{24} \\ \mathrm{In}\mathrm{descending}\mathrm{order}: \\ \frac{{\displaystyle -14}}{{\displaystyle 24}},\frac{{\displaystyle -9}}{{\displaystyle 24}},\frac{{\displaystyle -6}}{{\displaystyle 24}}. \end{gathered}$$
