1. The problem asks how dividing a number by 100 affects the position of the decimal point. 2. When you divide by 100, you are dividing by $10^2$. 3. Dividing by $10^2$ moves the decimal point two places to the left because each division by 10 moves the decimal one place left. 4. For example, dividing 345 by 100: $$345 \div 100 = 3.45$$ Here, the decimal moved from the end of 345 (which is 345.0) two places left to become 3.45. 5. Therefore, the correct answer is: Dividing by 100 moves the decimal two places to the left.
