Задание 472 найдити произведения

1) -1,9×0,6= -1,14
2) 6,5×(-30,8)= -200,2
3) -18,3×(-5,4)= 98,82
4) 5,9×(-3,5)= -20,65
5) -12,5×(-0,4)= 5
6) 5×(-9,3)= - 46,5
7)
$0.8 \times ( - \frac{1}{2} ) = \frac{8}{10} \times ( - \frac{1}{2} ) =$

$\frac{4}{10} \times( - \frac{1}{1} ) = - \frac{4}{10} = - 0.4$

8)
$( - \frac{3}{5} ) \times 0.75 = ( - \frac{3}{5} ) \times \frac{75}{100} =$

$( - \frac{3}{1} ) \times \frac{15}{100} = - \frac{45}{100} = - 0.45$

9)
$- 0.4 \times ( - \frac{1}{10} ) = - \frac{4}{10} \times ( - \frac{1}{10} ) =$

$= \frac{4}{100} = \frac{1}{25} = 0.04$
