Answer 1

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

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