1) \( \left( -\frac{2}{3} + \frac{3}{7} \right) \cdot \frac{4}{5} + \left( -\frac{1}{3} + \frac{4}{7} \right) \cdot 4 \cdot \frac{5}{5} \);
2) \( \frac{5}{9} \cdot \left( \frac{1}{11} + \frac{5}{22} \right) + \frac{5}{9} \cdot \left( \frac{1}{15} - \frac{2}{3} \right) \);
3) \( \left( \frac{1}{3} \cdot \frac{5}{12} \right) - 4 \cdot \left( \frac{3}{7} - \frac{17}{12} \right) \cdot 4 \cdot \frac{5}{5} \);
4) \( \frac{29}{49} + \frac{29}{34} - \frac{29}{32}; \)
5) \( \left( -\frac{7}{9} + \frac{3}{11} \right) \cdot \frac{3}{4} - \left( \frac{2}{9} \cdot \frac{19}{11} \right) \cdot 3 \cdot \frac{4}{5}; \)
6) \( 4 \cdot \frac{1}{5} + \frac{3}{10} - 4 \cdot \frac{3}{10} + \frac{3}{8} \cdot \frac{3}{10} \cdot 5. \)
