Вычисли частное следующих выражений: 5 2/4 : 2/15

- а) $5\frac{2}{4} : \frac{2}{15} = \frac{22}{4} : \frac{2}{15} = \frac{22}{4} * \frac{15}{2} = \frac{11}{2} * \frac{15}{1} = \frac{165}{2} = 82\frac{1}{2}$ - б) $2\frac{2}{3} : \frac{8}{9} = \frac{8}{3} : \frac{8}{9} = \frac{8}{3} * \frac{9}{8} = \frac{1}{1} * \frac{3}{1} = 3$ - в) $\frac{64}{131} : \frac{32}{52} = \frac{64}{131} * \frac{52}{32} = \frac{2}{131} * \frac{52}{1} = \frac{104}{131}$ - г) $\frac{64}{125} : 4 = \frac{64}{125} * \frac{1}{4} = \frac{16}{125} * \frac{1}{1} = \frac{16}{125}$ - д) $9 : \frac{3}{4} = 9 * \frac{4}{3} = 3 * 4 = 12$ - е) $9 : 4 = \frac{9}{4} = 2\frac{1}{4}$ - ж) $13\frac{1}{7} : 1\frac{1}{14} = \frac{92}{7} : \frac{15}{14} = \frac{92}{7} * \frac{14}{15} = \frac{92}{1} * \frac{2}{15} = \frac{184}{15} = 12\frac{4}{15}$ - з) $2\frac{1}{3} : 7\frac{1}{9} = \frac{7}{3} : \frac{64}{9} = \frac{7}{3} * \frac{9}{64} = \frac{7}{1} * \frac{3}{64} = \frac{21}{64}$
