Решение №1

а)

$$\frac{-3.8}{0.76} = \frac{-380}{76} = -5$$

б)

$$\frac{0.46}{-9.2} = \frac{46}{-920} = -0.05$$

в)

$$\frac{15.2}{-9.5} = \frac{152}{-95} = -1.6$$

г)

$$7,6 : (-1\frac{4}{15}) = 7,6 : (-\frac{19}{15}) = \frac{76}{10} : (-\frac{19}{15}) = \frac{76}{10} * (-\frac{15}{19}) = \frac{4}{2} * (-\frac{3}{1}) = -6$$
