ГДЗ по математике 6 класс Дорофеев Задание 936

\[\boxed{\mathbf{936\ (936)}\mathbf{.}\mathbf{\ }Еуроки\ - \ ДЗ\ без\ мороки}\]

\[\textbf{а)}\ a = - 3;\ \ b = 2:\]

\[\frac{a}{b} = \frac{- 3}{2} = - \frac{3}{2} = - 1,5.\]

\[\textbf{б)}\ a = 7,6;\ \ b = - 0,2:\]

\[\frac{a}{b} = \frac{7,6}{- 0,2} = - \frac{76}{2} = - 38.\]

\[\textbf{в)}\ a = - 8,2;\ \ \ b = - 0,2:\]

\[\frac{a}{b} = \frac{( - 8,2)}{- 0,2} = + \frac{82}{2} = 41.\]

\[\textbf{г)}\ a = - 4,5;\ \ b = - 0,09:\]

\[\frac{a}{b} = \frac{- 4,5}{- 0,09} = + \frac{450}{9} = 50.\]

\[\textbf{д)}\ a = 6,12;\ \ \ b = - 0,4:\]

\[\frac{a}{b} = \frac{6,12}{- 0,4} = - \frac{612}{40} = - \frac{153}{10} = - 15,3.\]

\[\textbf{е)}\ a = 0;\ \ b = - 8,9:\]

\[\frac{a}{b} = \frac{0}{- 8,9} = 0.\]
