Ta có:
\(\dfrac{3}{4};\dfrac{5}{6}< 1\) ; \(\dfrac{7}{6}>1\)
Mà \(\dfrac{3}{4}=\dfrac{9}{12}\) ; \(\dfrac{5}{6}=\dfrac{10}{12}\)
\(\Rightarrow\dfrac{9}{12}< \dfrac{10}{12}\Leftrightarrow\dfrac{3}{4}< \dfrac{5}{6}\)
Hay \(\dfrac{7}{6}>1>\dfrac{5}{6}>\dfrac{3}{4}\)
Vậy ta sắp xếp : \(\dfrac{7}{6};1;\dfrac{5}{6};\dfrac{3}{4}\)
Sắp xếp theo thứ tự giảm dần 7/8,8/7,1,3/4
