Question

вычислите
-0.3 : ((1 - 0.25) : (1 - 0,75)) =
-56.7 x (-6/7) =
-2 7/8 : (-16) =
-4.7 : (-5/8) =
2.44 x (-3 7/12) =
-2 7/10 x (-2.5) =

Answer 1

-0.3:((1-0.25):(1-0.75))=-0,1

-56.7х(-6/7)=243/5х

-2 7/8:(-16)=23/128

-4.7 : (-5/8) =188/25

2.44 x (-3 7/12) = 2.44х 43/12

-2 7/10 x (-2.5) =-27/10-2/5
