Answer 1

$- 40 \div ( - 5) = 8 \\ - 48.72 \div 12 = - 4.06 \\ - \frac{26}{63} \div ( - \frac{39}{49} ) = \frac{26 \times 49}{63 \times 39} = \frac{2 \times 7}{9 \times 3} = \frac{14}{27} \\ - 1 \frac{1}{14} \div 5 \frac{5}{7} = - \frac{15}{14} \div \frac{40}{7} = - \frac{15 \times 7}{14 \times 40} = - \frac{3 \times 1}{2 \times 8} = - \frac{3}{16}$
