1. Tính, tính nhầm
a) \( 2 \frac{15}{17} \) + \( 3 \frac{15}{19} \) + \( 16 \frac{1}{9} \)
b) \( \left( \frac{3}{5} - \frac{1}{3} \right)^2 \) + \( \frac{5}{8} \) + \( \frac{1}{2} \)
c) \( \frac{3}{7} \cdot \frac{23}{50} \) + \( \frac{14}{9} \) + \( \frac{100}{46} \) + \( \frac{11}{13} \)
2. Tìm x
a) \( \frac{1}{2} \left( x - \frac{3}{7} \right) = \frac{5}{6} \)
b) \( \frac{1}{2} \cdot x - \frac{3}{7} = \frac{5}{6} \)
c) \( \frac{1}{2} \left( x - \frac{3}{7} \right)^3 = \frac{1}{16} \)
