Bài 2: Tính nhanh

a) \(-\frac{5}{11} + \left( -\frac{6}{11} + 1 \right)\)
\(\frac{3}{4} \quad \frac{7}{25} \quad \frac{3}{4} \quad \frac{25}{25}\)

b) \(\frac{2}{3} \left( \frac{5}{7} - \frac{2}{3} \right)\)
\(7 \quad 3 \quad 7 \quad 18\)

c) \(\frac{\left( \frac{1}{4} + \frac{5}{8} \right)}{-\frac{3}{8}}\)
\(-\frac{3}{5} + \frac{5}{7} - \frac{3}{7} - \frac{3}{5} = 6\)

d) \( \frac{7}{5} + \frac{8}{7} + \frac{1}{5} + \frac{19}{5}\)
\(5 \quad 19 \quad 5 \quad 19\)
