1) $6 - \frac{3}{7} = \frac{6}{1} - \frac{3}{7} = \frac{42 - 3}{7} = \frac{39}{7} = 5\frac{4}{7}$

2) $8 - \frac{2}{3} = \frac{8}{1} - \frac{2}{3} = \frac{24-2}{3} = \frac{22}{3} =7 \frac{1}{3}$

3) $7 - \frac{5}{8} = \frac{7}{1}- \frac{5}{8} = \frac{56-5}{8} = \frac{51}{8} = 6\frac{3}{8}$

4) $2 - \frac{5}{6} = \frac{2}{1} - \frac{5}{6} = \frac{12-5}{6} = \frac{7}{6} = 1\frac{1}{6}$

5) $5 \frac{2}{3} - 4 = 1 \frac{2}{3}$

6) $12 \frac{1}{4} - 9 = 3 \frac{1}{4}$

7) $7 \frac{3}{4} - 4 = 3 \frac{3}{4}$

8) $6 - 1\frac{1}{2} = 4 \frac{1}{2}$

9) $4 - 2 \frac{3}{5} = 1 \frac{2}{5}$

10) $7 - 1 \frac{2}{3} =5 \frac{1}{3}$

11) $4 - 1 \frac{1}{6} = 2 \frac{5}{6}$
