Question

which is the same as moving the decimal point 3 places to the left in a decimal number? multiplying the number by 1,000 dividing the number by 1,000 dividing the number by 100 multiplying the number by 100

Explanation:

Step1: Recall decimal point movement rules

Moving the decimal point \( n \) places to the left in a number is equivalent to dividing the number by \( 10^n \).

Step2: Apply the rule for \( n = 3 \)

For \( n = 3 \), \( 10^3=1000 \). So moving the decimal point 3 places to the left is the same as dividing the number by 1000.

Answer:

B. Dividing the number by 1,000
