133. Выполните деление: a) 3/8: 2/3; 6) 4/7: 4/9; B) 1110: 3; 1) 1:8; д) 12:윽.

а) \(\frac{3}{8} : \frac{2}{3} = \frac{3}{8} \cdot \frac{3}{2} = \frac{9}{16}\)

б) \(\frac{4}{7} : \frac{4}{9} = \frac{4}{7} \cdot \frac{9}{4} = \frac{9}{7} = 1 \frac{2}{7}\)

в) \(11 \frac{2}{5} : 3 \frac{4}{5} = \frac{57}{5} : \frac{19}{5} = \frac{57}{5} \cdot \frac{5}{19} = \frac{57}{19} = 3\)

г) \(\frac{16}{17} : 8 = \frac{16}{17} \cdot \frac{1}{8} = \frac{2}{17}\)

д) \(12 : \frac{6}{7} = 12 \cdot \frac{7}{6} = 2 \cdot 7 = 14\)

Ответ: а) \(\frac{9}{16}\); б) 1 \(\frac{2}{7}\); в) 3; г) \(\frac{2}{17}\); д) 14.
