Решите задачу:

$( - \frac{5}{6} ) \div ( - \frac{5}{12} ) = \frac{5}{6} \times \frac{12}{5} = \frac{2}{1} = 2$

$( - 8 \frac{2}{5} ) \div 7 = - ( \frac{42}{5} \div \frac{7}{1} ) = - ( \frac{42}{5} \times \frac{1}{7} ) = - \frac{6}{5} = - 1 \frac{1}{5} = - 1.2$

$- 3 \frac{3}{4} \div 1 \frac{1}{2} = - ( \frac{15}{4} \div \frac{3}{2} ) = - ( \frac{15}{4} \times \frac{2}{3} ) = - \frac{5}{2} = - 2.5$

$( - 7 \frac{1}{6} ) \div ( - 5) = \frac{43}{6} \times \frac{1}{5} = \frac{43}{30} = 1 \frac{13}{30}$

$1 \frac{7}{9} \div ( - 2 \frac{2}{3}) = - ( \frac{16}{9} \times \frac{3}{8} ) = - \frac{2}{3}$

$4 \frac{2}{3} \div ( - 1 \frac{1}{6} ) = - ( \frac{14}{3} \times \frac{6}{7} ) = - \frac{4}{1} = - 4$
