Выполним деление дробей по порядку:
а) \[\frac{11}{8} : \frac{3}{4} = \frac{11}{8} \cdot \frac{4}{3} = \frac{11 \cdot 4}{8 \cdot 3} = \frac{44}{24} = \frac{11}{6} = 1\frac{5}{6}\]
б) \[\frac{3}{8} : \frac{9}{16} = \frac{3}{8} \cdot \frac{16}{9} = \frac{3 \cdot 16}{8 \cdot 9} = \frac{48}{72} = \frac{2}{3}\]
в) \[\frac{18}{5} : \frac{27}{10} = \frac{18}{5} \cdot \frac{10}{27} = \frac{18 \cdot 10}{5 \cdot 27} = \frac{180}{135} = \frac{4}{3} = 1\frac{1}{3}\]
г) \[\frac{36}{5} : \frac{9}{37} = \frac{36}{5} \cdot \frac{37}{9} = \frac{36 \cdot 37}{5 \cdot 9} = \frac{1332}{45} = \frac{444}{15} = \frac{148}{5} = 29\frac{3}{5}\]
Ответ: а) 1 5/6; б) 2/3; в) 1 1/3; г) 29 3/5
