1. The problem asks how dividing a number by 1,000 affects the position of the decimal point. 2. When dividing by powers of 10, the decimal point moves to the left by as many places as the number of zeros in the divisor. 3. Since 1,000 has three zeros, dividing by 1,000 moves the decimal point three places to the left. 4. For example, dividing 5,000 by 1,000: $$5000 \div 1000 = 5.000$$ The decimal moves from the end of 5000 (which is 5000.0) three places left to become 5.000. 5. Therefore, the correct statement is: Dividing by 1,000 moves the decimal three places to the left.
