г) $$3\frac{2}{5} - \frac{4}{5} = 2 \frac{7}{5} - \frac{4}{5} = 2 \frac{3}{5}$$

д) $$4\frac{1}{6} - 1\frac{5}{6} = 3 \frac{7}{6} - 1\frac{5}{6} = 2 \frac{2}{6} = 2 \frac{1}{3}$$

e) $$6\frac{6}{15} - 2\frac{9}{15} = 5 \frac{21}{15} - 2\frac{9}{15} = 3 \frac{12}{15} = 3 \frac{4}{5}$$

Ответ: г) $$2\frac{3}{5}$$; д) $$2\frac{1}{3}$$; e) $$3\frac{4}{5}$$
