$-3\frac{7}{16} + (-2\frac{5}{32}) = -(3\frac{14}{32} + 2\frac{5}{32}) = -5\frac{19}{32}$
$-4\frac{2}{9} + (-1\frac{17}{36}) = -(4\frac{8}{36} + 1\frac{17}{36}) = -5\frac{25}{36}$
$-7 + 1\frac{13}{16} = -(7 - 1\frac{13}{16}) = -(6\frac{16}{16} - 1\frac{13}{16}) = -5\frac{3}{16}$
$-1\frac{1}{12} + 3\frac{4}{9} = 3\frac{16}{36} - 1\frac{3}{36} = 2\frac{13}{36}$
$-5\frac{16}{21} + 2\frac{5}{9} = -(5\frac{48}{63} - 2\frac{35}{63}) = -3\frac{13}{63}$
$4\frac{9}{16} + (-9\frac{5}{6}) = -(9\frac{40}{48} - 4\frac{27}{48}) = -5\frac{13}{48}$
$3\frac{5}{17} + (-5\frac{8}{51}) = -(5\frac{8}{51} - 3\frac{15}{51}) = -(4\frac{59}{51} - 3\frac{15}{51}) = -1\frac{44}{51}$
$-2\frac{6}{7} + 6\frac{2}{3} = 6\frac{14}{21} - 2\frac{18}{21} = 5\frac{35}{21} - 2\frac{18}{21} = 3\frac{17}{21}$
