How to Multiply Decimals by 10, 100, and 1000: Step-by-Step Guide
FAQs on Multiplying Decimals by 10, 100, or 1000 – Class 6 Maths Practice
1. What is the rule for multiplying decimals by 10, 100, or 1000?
The main rule for multiplying decimals by powers of ten is to move the decimal point to the right. The number of places you move the decimal point is equal to the number of zeros in the multiplier (10, 100, or 1000).
- To multiply by 10, move the decimal point one place to the right.
- To multiply by 100, move the decimal point two places to the right.
- To multiply by 1000, move the decimal point three places to the right.
2. How do you multiply a decimal by 1000?
To multiply any decimal number by 1000, you simply shift the decimal point three places to the right. If there are not enough digits after the decimal, you can add placeholder zeros to the end of the number. For example, 4.52 × 1000 becomes 4520.
3. Why does the decimal point move when multiplying by 10, 100, or 1000?
The decimal point moves because of the concept of place value in our number system. Multiplying a number by 10, 100, or 1000 makes the number that many times larger. Shifting the decimal point to the right is a shortcut that reflects this increase in the value of each digit. For instance, multiplying by 10 moves a digit from the tenths place to the ones place, making its value ten times greater.
