Answer 1

Explicación paso a paso:

a)

$( - 4)(5)( - 3) = ( - 20)( - 3) = + 60$

b)

$( - 1)(3)( - 4)(2) \\ = ( - 3)( - 8) \\ = + 24$

c)

$(0.5)( - 0.8) \\ = ( \frac{5}{10} )( - \frac{8}{10} ) \\ = ( - \frac{40}{100} ) \\ = - \frac{4}{10} \\ = - 0.4$

d)

$(5)( - 2)( - 1)( - 8) \\ = ( - 10)( + 8) \\ = - 80$

e)

$(6)( - 3)(0)( - 9) \\ = ( - 18)(0) \\ = 0$

f)

$( -0.75)(0.6)( - 0.5) \\ = ( - \frac{75}{100} )( \frac{6}{10} )( - \frac{5}{10} ) \\ = ( - \frac{450}{1000} )( - \frac{5}{10} ) \\ = ( - \frac{45}{100} )( - \frac{5}{10} ) \\ = + \frac{225}{1000} \\ = + 0.225$
