$c, \frac{5}{6} = \frac{20}{24} T a c ó : 20 > 19 n ê n \frac{20}{24} > \frac{19}{24} h a y \frac{5}{6} > \frac{19}{24} V ậ y \frac{5}{6} > \frac{19}{24}$ .

Answer 3

$a, Q u y đ ồ n g : \frac{7}{9} = \frac{7 x 5}{9 x 5} = \frac{35}{45} \frac{2}{5} = \frac{2 x 9}{5 x 9} = \frac{18}{45} S o s á n h : c ó 35 > 18 \Rightarrow \frac{35}{45} > \frac{18}{45} \Rightarrow \frac{7}{9} > \frac{2}{5} b, c ó \frac{11}{6} > 1 \frac{7}{9} < 1 \Rightarrow \frac{11}{6} > \frac{7}{9} c, Q u y đ ồ n g : \frac{5}{6} = \frac{5 x 4}{6 x 4} = \frac{20}{24} c ó 20 > 19 \Rightarrow \frac{20}{24} > \frac{19}{24} \Rightarrow \frac{5}{6} > \frac{19}{24}$ .
