Find the quotients in each group below. is division commutative?

- 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)

answer: the answer is (b) amie should have multiplied

step-by-step explanation: given a sphere and a cylinder with same radius and height.

let, 'r' be the radius of the cylinder and sphere and 'h' be the height of the cylinder. according to the question,

r = h.

now, the volume of the sphere will be

and the volume of the cylinder will be

therefore, we have

thus, ammie should have multiplied the volume of the sphere

-9
