Answer:

B, C

Explanation:

A.) When you multiply 32.4 x 103, the decimal moves 3 places to the right.


32.4 \cdot 103 = 3337.2

No, it is 2 places to the right.

B.) When you divide 32.4 by 102, the decimal moves two places to the left.


$(32.4)/(102) \approx 0.32$

Yes. If we consider 32.4 and 0.32.


32.4 = 0.324 \cdot 10^2

We obtain 0.32 by moving the number 32 decimal two places to the left

C.) When you multiply 0.32 x 102, the decimal moves 2 places to the right.


0.32 \cdot 102 = 32.64

Yes

D.) When you multiply 3.24 by 102, the answer is 3,240.


3.24 \cdot 102 = 330.48

No

E.) When you divide 324 by 102, the answer is 3.24.


$(324)/(102) = 3.176...$

No
