Answer 1

Ответ:

$a) - 3.2 \times 6x \\ - (3.2 \times 6)x \\ = - 19.2x \\ b) - 0.8 + ( - 0.7) \\ 0.8 \times 0.7 = 0.56 \\ d)5a \times ( - 1.4b) \times 0.6c \\ - 5a \times 1.4 \times 0.6c = - 4.2ac \\ g) \frac{15}{56} \times( - x) \times \frac{28}{30} \times y \\ - \frac{1}{2} x \times \frac{1}{2} y = - \frac{1}{4} xy \\ e) - 16m \times 1.5n \\ - (1.6 \times 1.5)mn = - 24mn \\ i) - \frac{35}{72} c \times 3 \frac{3}{7} d \\ - \frac{5}{24}c \times 3d = - \frac{5}{8} cd$
