Answer:
- 2 ÷ 3 = - 0.667 and 3 ÷ (- 2) = - 1.5.
- 12 ÷ (- 4) = 3 and - 4 ÷ (- 12) = 0.333.
16 ÷ 8 = 2 and 8 ÷ 16 = 0.5.
Division is not commutative.
Step-by-step explanation:
We have to find the quotients in each group as given in the attachment.
- 2 ÷ 3 = - 0.667 and 3 ÷ (- 2) = - 1.5. So, - 2 ÷ 3 ≠ 3 ÷ (- 2)
- 12 ÷ (- 4) = 3 and - 4 ÷ (- 12) = 0.333. So, - 12 ÷ (- 4) ≠ - 4 ÷ (- 12)
Now, 16 ÷ 8 = 2 and 8 ÷ 16 = 0.5. So, 16 ÷ 8 ≠ 8 ÷ 16
From the above examples, we can say division is not commutative. (Answer)

We have similar triangle trianges ABC ~ ADE so
BC:AB = DE:AD
BC:2 = 10 : (2+3) = 10:5 = 2:1
So BC=4 because 4:2 = 2:1
Choice C.
