Пошаговое объяснение:

[tex]1) - 6.8 \div 2 = - 3.4[/tex]

[tex]2) - \frac{1}{9} \div ( - \frac{1}{3} ) = - \frac{1}{9} \times ( - \frac{3}{1} ) = - \frac{1}{3} \times ( - \frac{1}{1} ) = \frac{1}{3} [/tex]

[tex]3) - 9 \div 3 = - 3[/tex]

[tex]4) \frac{5}{6} \div ( - 10) = \frac{5}{6} \div ( - \frac{10}{1} ) = \frac{5}{6} \times ( - \frac{1}{10} ) = \frac{1}{6} \times ( - \frac{1}{2} ) = - \frac{1}{12} [/tex]

[tex]5) - \frac{5}{6} \div ( - 2 \frac{1}{12} ) = - \frac{5}{6} \div ( - \frac{25}{12} ) = - \frac{5}{6} \times ( - \frac{12}{25} ) = - \frac{1}{1} \times ( - \frac{2}{5} ) = \frac{2}{5} = \frac{4}{10} = 0.4[/tex]

[tex]6) - 4.8 \div ( - 30) = 0.16[/tex]
