Bài 2: Thực hiện phép tính
1) \(\frac{3}{7} \left( \frac{2}{3} - \frac{1}{4} \right) + \frac{3}{7} \left( \frac{1}{3} + \frac{1}{4} \right)\)
3) \(\left( \frac{15}{11} - \frac{4}{13} \right) \frac{12}{17} + \frac{12}{11} \left( \frac{9}{13} - \frac{12}{17} \right)\)
5) \(15 \left( \frac{3}{24} - \frac{1}{12} \right) + 15 \left( \frac{11}{6} - \frac{7}{8} \right)\)
7) \(-\frac{3}{7} - \frac{5}{11} + \left( -\frac{4}{7} + \frac{6}{11} \right) \times -\frac{5}{3}\)
9) \(\frac{1}{5} - \left( \frac{20}{21} - \frac{-40}{45} \right) \frac{20}{21}\)
Thực hiện kết thúc.
2) \(\frac{51}{61} \left( \frac{1}{4} - \frac{2}{5} \right) + \frac{51}{61} \left( \frac{3}{4} + \frac{5}{7} \right)\)
4) \(\frac{9}{5} \left( \frac{9}{-18} \right) + \frac{9}{5} \left( \frac{5}{36} - \frac{12}{12} \right)\)
6) \(\left( \frac{15}{11} - \frac{4}{13} \right) \frac{12}{17} + \frac{7}{11} \left( \frac{9}{13} - \frac{1}{17} \right)\)
8) \(\left( \frac{7}{6} - \frac{20}{21} \right) + \frac{5}{11} \left( \frac{6}{21} - \frac{20}{21} \right)\)
10) \(\left( \frac{7}{2} + \frac{1}{3} \right) - \left( \frac{11}{23} - \frac{2}{3} \right)\)
