$-5\frac{7}{10} + 3\frac{14}{15} = -5\frac{21}{30} + 3\frac{28}{30} = -4\frac{51}{30} + 3\frac{28}{30} = -1\frac{23}{30}$
$3\frac{5}{12} - 4\frac{9}{16} = 3\frac{20}{48} - 4\frac{27}{48} = -1\frac{7}{48}$
$-3\frac{1}{6} - 1\frac{3}{4} = -3\frac{2}{12} - 1\frac{9}{12} = -4\frac{11}{12}$
$-5\frac{7}{8} + \frac{9}{10} = -5\frac{35}{40} + \frac{36}{40} = -4\frac{75}{40} + \frac{36}{40} = -4\frac{39}{40}$
$2\frac{3}{8} + 3\frac{5}{12} - 6\frac{3}{16} = 2\frac{18}{48} + 3\frac{20}{48} - 6\frac{9}{48} = 5\frac{38}{48} - 5\frac{57}{48} = -\frac{19}{48}$
$3\frac{4}{15} - 8\frac{1}{12} + 1\frac{7}{30} = 3\frac{16}{60} - 8\frac{5}{60} + 1\frac{14}{60} = 4\frac{30}{60} - 7\frac{65}{60} = -3\frac{35}{60} = -3\frac{7}{12}$
$3\frac{1}{2} - 2\frac{5}{6} - 1\frac{4}{9} = 3\frac{9}{18} - 2\frac{15}{18} - 1\frac{8}{18} = 3\frac{9}{18} - 3\frac{23}{18} = -\frac{14}{18} = -\frac{7}{9}$
$5\frac{1}{4} - 2\frac{1}{12} - 4\frac{2}{3} = 5\frac{3}{12} - 2\frac{1}{12} - 4\frac{8}{12} = 3\frac{2}{12} - 4\frac{8}{12} = -1\frac{6}{12} = -1\frac{1}{2}$
