г) $$(3 \frac{5}{8} + 2 \frac{2}{13}) - (2 \frac{7}{8} + 1 \frac{2}{13}) = 3 \frac{5}{8} + 2 \frac{2}{13} - 2 \frac{7}{8} - 1 \frac{2}{13} = (3 \frac{5}{8} - 2 \frac{7}{8}) + (2 \frac{2}{13} - 1 \frac{2}{13}) = (3 - 2 + \frac{5}{8} - \frac{7}{8}) + (2 - 1 + \frac{2}{13} - \frac{2}{13}) = (1 - \frac{2}{8}) + (1 + 0) = 1 - \frac{1}{4} + 1 = 2 - \frac{1}{4} = 1 \frac{3}{4} $$
Ответ: $$1 \frac{3}{4}$$
