Пошаговое объяснение:

1) -1.4+0.8=-0.6

2)  -8.9x = 17.889 ⇒  x = -(17.889/ 8.9) = -2.01

3) (-(-(-(0.6)))) -0,6 = (-(-(-0.6))) -0.6 = (-(0.6))-0.6 = -0.6-0.6 = -1.2

4) 18.25 - 11.6 - 23.05 = -16.4

5)

A) -60 : (-0.5) = 120

B) -3.6 : (-3) = 1.2

C) -0.48 : (-0.04) = 12

D) -2.4 * (-0.5) = 1.2

6)

$(-0.25+\frac{7}{8} ): (-1\frac{1}{4} )=(-\frac{1}{4} +\frac{7}{8} ):(-1\frac{1}{4} )=\frac{-2+7}{8} :(\frac{-5}{4} ) =\frac{5}{8} :(\frac{-5}{4} ) =-\frac{5*4}{8*5} = -\frac{1}{2}$
