Answer 1

Если что непонятно, пиши)

Answer 2

(2,1)∙(- 5/9 ): (-0,15)=
1)
2,1*(-5/9)=21/10*(-5/9)=-21/18=-7/6=-1 целая 1/6
2)-7/6/(-0,15)=7/6/3/20=7/6*20/3=140/18=70/9=7 целых 7/9

Answer 3

I'm assuming you meant to write (2,1)∙(-5/9) : (-0.15) with a dot representing scalar multiplication and a colon representing division.

In that case, the expression simplifies as follows:

(2,1)∙(-5/9) = (-10/9, -5/9)

And

(-10/9, -5/9) : (-0.15) = (-10/9, -5/9) * (-1/0.15) = (20/3, 1/3)

Therefore, (2,1)∙(-5/9) : (-0.15) = (20/3, 1/3).
