Answer 1

$- 8.4 \div ( - 0.7) = - 84 \div ( - 7) = 12$

$8.88 \div ( - 2.4) = 88.8 \div ( - 24) = - 3.7$

$- 3.289 \div 1.3 = - 32.89 \div 13 = - 2.53$

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

$15 \div ( - \frac{5}{7} ) = - \frac{15 \times 7}{5 } = - 3 \times 7 = - 21$

$- \frac{6}{7} \div 12 = - \frac{6}{7 \times 12} = - \frac{1}{7 \times 2} = - \frac{1}{14}$
