Ответ:
Решение:
- \( \frac{4}{8} - \frac{7}{4} = \frac{1}{2} - \frac{7}{4} = \frac{2}{4} - \frac{7}{4} = \frac{2-7}{4} = -\frac{5}{4} = -1\frac{1}{4} \)
- \( -3\frac{3}{8} - 2\frac{5}{8} = -3 - \frac{3}{8} - 2 - \frac{5}{8} = -5 - \frac{3+5}{8} = -5 - \frac{8}{8} = -5 - 1 = -6 \)
- \( -3\frac{5}{8} \)
- \( 12\frac{1}{8} \)
