How Does Multiplying Decimals by 10, 100, or 1000 Move the Decimal Point?
FAQs on Practice Multiplying Decimals by 10, 100, and 1000
1. How do you multiply decimals with 10, 100, and 1000?
To multiply decimals by 10, 100, and 1000, you simply move the decimal point to the right. This is a fast method for Class 5 maths based on understanding place value.
- 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.
For example, in the exercise 3.452 × 100, you move the decimal two places to get 345.2.
2. What is the easiest way to teach multiplying decimals to a Class 5 student?
The easiest way to teach multiplying decimals for Class 5 is by using the 'decimal shift' or 'decimal jump' method. This visual trick helps students understand how the value of a number changes when multiplied by powers of ten.
- Rule 1 (x 10): The decimal point 'jumps' one place to the right.
- Rule 2 (x 100): The decimal point 'jumps' two places to the right.
- Rule 3 (x 1000): The decimal point 'jumps' three places to the right.
Using a practice worksheet with these rules helps reinforce the concept.
3. Why does the decimal point move when multiplying by 10, 100, or 1000?
The decimal point moves to the right because multiplying by 10, 100, or 1000 increases the value of each digit. This core concept is tied to the decimal place value system.
- When you multiply by 10, each digit moves one place value to the left, becoming ten times larger (e.g., the digit in the tenths place moves to the ones place).
- This shift in the digits' values makes the decimal point appear to move to the right. For example, 5.67 x 10 = 56.7.

7. What mathematical skills does this worksheet on multiplying decimals by 10, 100, and 1000 build?
This worksheet builds several foundational maths skills essential for Grade 5 students. It goes beyond simple calculation to reinforce a deeper understanding of the number system.
- Place Value: It strengthens the understanding of how a digit's position determines its value.
- Number Patterns: It helps students recognise patterns when multiplying by powers of 10.
- Decimal Operations: It provides a solid base for more complex decimal calculations, such as division.
- Mental Maths: It encourages students to find answers quickly without a calculator.
8. How is multiplying a decimal by 10 different from multiplying a whole number by 10?
While the principle of increasing a number's value is the same, the common method appears different. This worksheet focuses on the method for decimals.
- For a whole number (e.g., 42), you typically add a zero at the end to multiply by 10 (42 × 10 = 420).
- For a decimal number (e.g., 4.2), you move the decimal point one place to the right (4.2 × 10 = 42). Simply adding a zero (4.20) does not change its value.
9. Can this Class 5 maths worksheet be used on a tablet?
Yes, this maths worksheet for Class 5 can be used digitally on a tablet or computer. Because it is a downloadable PDF, you can open it in any PDF reader or annotation app to write the answers directly on the screen, making it a flexible tool for modern learning environments.
