**Phần 2. TỰ LUẬN**
Câu 1. Thực hiện phép tính
a) \( \frac{4}{5} + \frac{-3}{4} - \frac{1}{3} \)
\[
\left[ \left( \frac{5}{3} + \frac{1}{4} \right)^{2} \cdot \frac{12}{5} - \frac{1}{2} \right]
\]
b) \( \frac{3}{5} - 1.25 \cdot \left( \frac{2}{5} \right)^{2} \)
c) \( \frac{-7}{8} + \frac{1}{2} + \left( \frac{-15}{8} + \frac{1}{4} \right) \cdot \frac{1}{7} \)
d) \( \frac{1}{7} \cdot \left( \frac{-7}{8} + \frac{1}{2} + \left( \frac{-15}{8} + \frac{1}{4} \right) \cdot \frac{1}{7} \right) \)
e) \( \left( \frac{-2}{3} + \frac{3}{4} \right) \cdot \frac{4}{5} \)
f) \( \left( \frac{1}{4} \right)^{2} \cdot \frac{4}{11} + \frac{7}{11} - \left( \frac{1}{4} \right)^{2} \)
g)
\[
\frac{29}{49} + \frac{29}{51} + \frac{29}{32}
\]
h)
\[
\frac{1}{5} + \frac{3}{10} - \frac{4}{3} + \frac{3}{8}
\]

**Câu 2. Tìm x biết**
\[
\frac{29}{19} + \frac{49}{51} + \frac{29}{19} + \frac{32}{51}
\]
