7/9<8/9

Có : 7<8

\(\Rightarrow\dfrac{7}{9}< \dfrac{8}{9}\)

\(\dfrac{7}{9}< \dfrac{8}{9}\)

a) \(\dfrac{5}{9}< \dfrac{7}{9}\)

b) \(\dfrac{7}{6}>\dfrac{6}{6}\)

c) \(\dfrac{3}{14}< \dfrac{5}{14}\)

d) \(\dfrac{5}{8}< \dfrac{9}{8}\)

6/8 < 9/5

vì : \(\dfrac{6}{8}< 1;\dfrac{9}{5}>1\\ \Rightarrow\dfrac{6}{8}< \dfrac{9}{5}\)

6/8<9/5

\(\dfrac{3}{8}< \dfrac{9}{6}\)
