в) $8\frac{3}{17} * 5\frac{1}{4} + 3\frac{14}{17} * 5\frac{1}{4}$;
г) $3\frac{4}{13} * 15\frac{3}{41} - 3\frac{4}{13} * 2\frac{3}{41}$;
д) $(2\frac{3}{4} + 4\frac{1}{8}) * 1\frac{5}{11}$;

$(3\frac{3}{5} - 2\frac{1}{15}) * 5 = (3\frac{9}{15} - 2\frac{1}{15}) * 5 = 1\frac{8}{15} * 5 = 1 * 5 + \frac{8}{15} * 5 = 5 + \frac{8}{3} = 5 + 2\frac{2}{3} = 7\frac{2}{3}$
$(1\frac{14}{17} - 1\frac{1}{34}) * 34 = (1\frac{28}{34} - 1\frac{1}{34}) * 34 = \frac{27}{34} * 34 = 27$
$8\frac{3}{17} * 5\frac{1}{4} + 3\frac{14}{17} * 5\frac{1}{4} = (8\frac{3}{17} + 3\frac{14}{17}) * 5\frac{1}{4} = 11\frac{17}{17} * 5\frac{1}{4} = 12 * 5 + 12 * \frac{1}{4} = 60 + 3 = 63$
$3\frac{4}{13} * 15\frac{3}{41} - 3\frac{4}{13} * 2\frac{3}{41} = 3\frac{4}{13} * (15\frac{3}{41} - 2\frac{3}{41}) = 3\frac{4}{13} * 13 = 3 * 13 + \frac{4}{13} * 13 = 39 + 4 = 43$
$(2\frac{3}{4} + 4\frac{1}{8}) * 1\frac{5}{11} = (2\frac{6}{8} + 4\frac{1}{8}) * 1\frac{5}{11} = 6\frac{7}{8} * 1\frac{5}{11} = \frac{55}{8} * \frac{16}{11} = \frac{5}{1} * \frac{2}{1} = 5 * 2 = 10$
$1\frac{2}{5} * (1\frac{1}{14} - \frac{5}{7}) = 1\frac{2}{5} * (1\frac{1}{14} - \frac{10}{14}) = 1\frac{2}{5} * (\frac{15}{14} - \frac{10}{14}) = 1\frac{2}{5} * \frac{5}{14} = \frac{7}{5} * \frac{5}{14} = \frac{1}{1} * \frac{1}{2} = \frac{1}{2}$
