Answer 1

Explicație pas cu pas:

a)1,(2)×3,14=1 2/9×3,14=(11/9)×3,14=3,837

b)(-5,6)×0,(6)=-5,6×6/9=-5,6×2/3=-3,73

c)(-1,1)×(-2,(3))=-1,1×(-2 3/9)=-1,1×(-2 1/3)=

1,1×7/3=7,7/3=2,56

d)3,(2)×(-1,4(3))=3 2/9×(-1 (43-4)/90)=

29/3× (-1 39/90)=29/3×(-1 13/30)=

-29/3×(43/30)=(-29×43)/(3×30)=

-1247/90=-13,85
