Answer 1

$\frac{1}{2} - 4 = \frac{1}{2} - 3 \frac{2}{2} = - 3 \frac{1}{2} \\ - \frac{5}{11} + \frac{5}{11} = 0 \\ - 5 + 2 \frac{1}{3} = - 4 \frac{3}{3} + 2 \frac{1}{3} = - 2 \frac{2}{3} \\ - 8 + \frac{1}{7} = - 7 \frac{7}{7} + \frac{1}{7} = - 7 \frac{6}{7} \\ \frac{1}{6} - 3 = \frac{1}{6} - 2 \frac{6}{6} = - 2 \frac{5}{6} \\ - \frac{5}{12} + 4 = - \frac{5}{12} + 3 \frac{12}{12} = 3 \frac{7}{12}$
