Answer:
B, C
Step-by-step explanation:
A.) When you multiply 32.4 x 103, the decimal moves 3 places to the right.
[tex]32.4 \cdot 103 = 3337.2[/tex]
No, it is 2 places to the right.
B.) When you divide 32.4 by 102, the decimal moves two places to the left.
[tex]$\frac{32.4}{102} \approx 0.32$[/tex]
Yes. If we consider 32.4 and 0.32.
[tex]32.4 = 0.324 \cdot 10^2[/tex]
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.
[tex]0.32 \cdot 102 = 32.64[/tex]
Yes
D.) When you multiply 3.24 by 102, the answer is 3,240.
[tex]3.24 \cdot 102 = 330.48[/tex]
No
E.) When you divide 324 by 102, the answer is 3.24.
[tex]$\frac{324}{102} = 3.176...$[/tex]
No
