Вычисление модулей:
- \( |-24| + |0| + |47| = 24 + 0 + 47 = 71 \)
- \( |-50:4| - |8| - |-4,5| = |-12,5| - 8 - 4,5 = 12,5 - 8 - 4,5 = 0 \)
- \( |5 - 7 : |2| - \frac{1}{9}| = |5 - 3,5 - \frac{1}{9}| = |1,5 - \frac{1}{9}| = |\frac{3}{2} - \frac{1}{9}| = |\frac{27-2}{18}| = |\frac{25}{18}| = \frac{25}{18} \)
- \( |5 - \frac{4}{7} - 3 \frac{1}{2}| + |-0,3| = |5 - \frac{4}{7} - \frac{7}{2}| + 0,3 = |\frac{70 - 8 - 49}{14}| + 0,3 = |\frac{13}{14}| + 0,3 = \frac{13}{14} + \frac{3}{10} = \frac{65 + 21}{70} = \frac{86}{70} = \frac{43}{35} \)
Ответ: 1. 71; 2. 0; 3. \(\frac{25}{18}\); 4. \(\frac{43}{35}\).
