**Bài 1: Thực hiện phép tính**
1) \( 2 \frac{6}{7} - \frac{3}{5} \)
2) \( -\frac{7}{3} + \frac{17}{12} \)
3) \( 1 \frac{1}{2} + \frac{3}{4} \)
4) \( \frac{12}{3} - \frac{5}{6} \)
5) \( 2 \frac{3}{4} \div \frac{45}{6} \)
6) \( 4 \frac{1}{2} - \frac{2}{3} \)
7) \( x + \frac{3}{4} = \frac{5}{12} \)
8) \( x - \frac{3}{5} = \frac{-11}{12} \)
9) \( x + \frac{7}{12} = \frac{5}{9} \)
10) \( x - \frac{1}{2} = \frac{5}{12} \)
11) \( 5 - \frac{3}{7} = x \)
12) \( -\frac{2}{7} + \frac{5}{9} = x \)
13) \( \frac{3}{7} + \frac{5}{3} = x \)
14) \( x + \frac{5}{7} = \frac{3}{3} \)
15) \( x - \frac{1}{7} = \frac{3}{3} \)
