Step-by-step explanation:
Here is your first answer:
First find whats common which is 6:
-4×2=-8
3×2=6
-3×3=-9

But use KCC which makes the equation...
-9+8=-1
-1/6
Here is your second answer:
First use KCC to Chang the equation into...
-3.9
-8.9
Then add:
9+9=18
=-1.28
Here is your third answer:
First change the equation (KCC):
2.9
9.4
9+4=13
3.9=12
=1.23
There are your answers:
I think the total may be 20/28..but idk
