\(\dfrac{7}{6}=\dfrac{7\times14}{6\times14}=\dfrac{98}{84};\dfrac{3}{4}=\dfrac{3\times21}{4\times21}=\dfrac{63}{84};\dfrac{6}{7}=\dfrac{6\times12}{7\times12}=\dfrac{72}{84};\dfrac{2}{7}=\dfrac{2\times12}{7\times12}=\dfrac{24}{84};\dfrac{2}{3}=\dfrac{2\times28}{3\times28}=\dfrac{56}{84};\dfrac{1}{3}=\dfrac{1\times28}{3\times28}=\dfrac{28}{84}\)
Vì \(\dfrac{98}{84}>\dfrac{72}{84}>\dfrac{63}{84}>\dfrac{56}{84}>\dfrac{28}{84}>\dfrac{24}{84}\Rightarrow\dfrac{7}{6}>\dfrac{6}{7}>\dfrac{3}{4}>\dfrac{2}{3}>\dfrac{1}{3}>\dfrac{2}{7}\)
Sắp xếp: \(\dfrac{7}{6};\dfrac{6}{7};\dfrac{3}{4};\dfrac{2}{3};\dfrac{1}{3};\dfrac{2}{7}\)
\(\dfrac{7}{6}>\dfrac{6}{7}>\dfrac{3}{4}>\dfrac{2}{3}>\dfrac{1}{3}>\dfrac{2}{7}\)
