Ответ:
Решение:
- \( -\frac{1}{4} - \left(-\frac{1}{3}\right) = -\frac{1}{4} + \frac{1}{3} = \frac{-3+4}{12} = \frac{1}{12} \)
- \( -\frac{2}{5} + \frac{1}{10} = \frac{-4+1}{10} = -\frac{3}{10} \)
- \( -\frac{3}{8} - \frac{1}{6} = \frac{-9-4}{24} = -\frac{13}{24} \)
- \( 11 - \frac{7}{15} = \frac{165-7}{15} = \frac{158}{15} \)
