Answer 1

Ответ:

$a) \: - 1.2 \times ( - 0.8) = 0.96$

$d) \: \frac{2}{9} \times ( - 1 \frac{2}{7} ) = \frac{2}{9} \times ( - \frac{9}{7} ) = - \frac{2}{7}$

$c) \: - 5.6 \times ( - \frac{3}{7}) = - \frac{56}{10} \times ( - \frac{3}{7} ) = 2.4$

$b) - 12.5 \times 3.6 = - 45$

$e) \: 1.2 \times ( - \frac{5}{8} ) = \frac{12}{10} \times ( - \frac{5}{8} ) = - \frac{3}{4}$

$f) \: - 4 \frac{2}{3} \times 1 \frac{2}{7} = - \frac{14}{3} \times \frac{9}{7} = - 4$
