1) $-\frac{3}{8} * \frac{5}{6}$
2) $-\frac{14}{15} * (-\frac{3}{7})$
3) $\frac{18}{55} * (-\frac{11}{18})$
4) $-\frac{21}{32} * (-\frac{12}{35})$
5) $\frac{17}{40} * (-\frac{8}{51})$
6) $-\frac{15}{22} * \frac{4}{27}$
$-\frac{3}{8} * \frac{5}{6} = -\frac{1}{8} * \frac{5}{2} = -\frac{5}{16}$
$-\frac{14}{15} * (-\frac{3}{7}) = \frac{2}{5} * \frac{1}{1} = \frac{2}{5}$
$\frac{18}{55} * (-\frac{11}{18}) = \frac{1}{5} * (-\frac{1}{1}) = -\frac{1}{5}$
$-\frac{21}{32} * (-\frac{12}{35}) = \frac{3}{8} * \frac{3}{5} = \frac{9}{40}$
$\frac{17}{40} * (-\frac{8}{51}) = \frac{1}{5} * (-\frac{1}{3}) = -\frac{1}{15}$
$-\frac{15}{22} * \frac{4}{27} = -\frac{5}{11} * \frac{2}{9} = -\frac{10}{99}$
