Bài 1. Thực hiện phép tính:
a) \(-\frac{9}{7} \left( \frac{14}{15} + \frac{7}{9} \right)\)
b) \(\left( \frac{2}{3} \frac{6}{5} \right) - \frac{15}{-36}\)
c) \(\left( \frac{3}{29} - \frac{1}{5} \right) \cdot \frac{3}{29}\)
d) \(\left(-\frac{2}{5} + \frac{1}{3} \right) \cdot \left( -\frac{3}{2} - \frac{3}{7} \right)\)
e) \(\left( \frac{1}{2} - \frac{1}{3} \right) \cdot \left( 5 - \frac{1}{4} \right)\)
f) \(\left( \frac{3}{2} \right)^{2} \cdot \frac{8}{3} \cdot \left( -\frac{3}{5} \right)^{2}\)
