Решим каждый пример по отдельности:
д) $$4\frac{9}{16} - 2\frac{3}{14} = 4\frac{63}{112} - 2\frac{24}{112} = (4-2) + (\frac{63}{112} - \frac{24}{112}) = 2 + \frac{39}{112} = 2\frac{39}{112}$$
е) $$11\frac{7}{32} - 9\frac{11}{64} = 11\frac{14}{64} - 9\frac{11}{64} = (11-9) + (\frac{14}{64} - \frac{11}{64}) = 2 + \frac{3}{64} = 2\frac{3}{64}$$
ж) $$17\frac{2}{3} - 6\frac{7}{8} = 17\frac{16}{24} - 6\frac{21}{24} = 16\frac{16+24}{24} - 6\frac{21}{24} = 16\frac{40}{24} - 6\frac{21}{24} = (16-6) + (\frac{40}{24} - \frac{21}{24}) = 10 + \frac{19}{24} = 10\frac{19}{24}$$
з) $$24\frac{7}{15} - 15\frac{5}{12} = 24\frac{28}{60} - 15\frac{25}{60} = (24-15) + (\frac{28}{60} - \frac{25}{60}) = 9 + \frac{3}{60} = 9 + \frac{1}{20} = 9\frac{1}{20}$$
в) $$1 + 3\frac{5}{6} = 4\frac{5}{6}$$
