How Does Dividing Decimals by 10, 100, or 1000 Move the Decimal Point?
FAQs on Practice Dividing 1–3 Digit Decimals by 10, 100, and 1000
1. How do you divide decimals by 10, 100, and 1000?
To divide decimals by 10, 100, and 1000, you simply move the decimal point to the left. The number of places you move the decimal depends on the number of zeros in the divisor.
- To divide by 10: Move the decimal point one place to the left.
- To divide by 100: Move the decimal point two places to the left.
- To divide by 1000: Move the decimal point three places to the left.
2. What happens to the decimal point when dividing by 10, 100, or 1000?
When you divide a decimal number by 10, 100, or 1000, the decimal point moves to the left. This movement makes the number smaller, reflecting the division. The number of places the decimal point shifts is equal to the number of zeros in the divisor (10, 100, or 1000), which is a key concept of decimal place value.
3. Why is dividing by 10, 100, and 1000 easier with decimals?
Dividing decimals by these numbers is easier because it does not require long division. Instead of performing complex calculations, you only need to apply the rule of decimal point movement. This is a simple trick based on the base-10 nature of our place value system, making mental calculations quick and efficient.
4. What is the rule for dividing a 3-digit decimal by 1000?
The rule for dividing any decimal by 1000 is to move the decimal point three places to the left. If there are not enough digits, you must add placeholder zeros to the left of the number before placing the decimal point.
For example, to solve 123.4 ÷ 1000, you move the decimal three places to the left to get 0.1234.
