$-3 * \frac{5}{16} = -\frac{15}{16}$
$\frac{7}{24} * (-8) = \frac{7}{3} * (-1) = -\frac{7}{3} = -2\frac{1}{3}$
$-\frac{13}{15} * (-30) = \frac{13}{1} * 2 = 26$
$18 * (-\frac{7}{12}) = 3 * (-\frac{7}{2}) = -\frac{21}{2} = -10\frac{1}{2}$
$-2\frac{6}{7} * (-\frac{12}{35}) = \frac{20}{7} * \frac{12}{35} = \frac{4}{7} * \frac{12}{7} = \frac{48}{49}$
$-2\frac{3}{8} * 1\frac{13}{19} = -\frac{19}{8} * \frac{32}{19} = -\frac{1}{1} * \frac{4}{1} = -4$
$-5\frac{1}{16} * (-1\frac{11}{45}) = \frac{81}{16} * \frac{56}{45} = \frac{9}{2} * \frac{7}{5} = \frac{63}{10} = 6\frac{3}{10}$
$-2\frac{1}{3} * (-1\frac{3}{14}) = \frac{7}{3} * \frac{17}{14} = \frac{1}{3} * \frac{17}{2} = \frac{17}{6} = 2\frac{5}{6}$
