Answer 3

I think for problem 1 it would be A. Why? Because when you divide -27 by 3 you get -9, so... I would believe that would conclude if you were to reverse the problem, where you multiply -9 by 3 that would be -9 - 9 - 9 = -27.
So... for the others, what do you think?

Answer 4

what about the other two

Answer 5

like give me some tips

Answer 6

Okay, for problem 4):
-32 is divided into 2 groups of -16.
As I explained with the first one:
-27 / 3 = -9 (So your dividend which is '3' is your group amount, -9 is the number you're working with, like the number that is being 'grouped', to get you the '3 groups of -9'. And -27 is just a number you are working with.)
Do you get that?
So...:
If '2' is your groups, -16 is the number being grouped, and -32 is just a number you are working with, what does that mean?
