Question

помогите пожалуйста ​

Answer 1

Ответ:

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

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

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

$b) - 12.5 times 3.6 = - 45$

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

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