How to Use the Distributive Property to Solve Multiplication Problems
FAQs on Multiplication in Parts Using the Distributive Property – Class 6 Worksheet
1. What is the distributive property of multiplication in Class 6 Maths?
The distributive property of multiplication is a fundamental rule in Class 6 Maths that helps simplify complex multiplication problems by breaking them down into easier parts. It states that multiplying a number by a sum or difference is the same as multiplying the number by each part of the sum or difference separately and then adding or subtracting the results. This is a key concept aligned with NCERT and CBSE standards.
2. How do you solve multiplication using the distributive law?
You can solve multiplication using the distributive law by breaking one of the numbers into simpler parts (like tens and ones), multiplying each part, and then combining the results. This step-by-step multiplication process makes mental math easier.
For example, to solve 23 × 6:
- Step 1: Break down 23 into (20 + 3).
- Step 2: Distribute the 6 to both parts: (6 × 20) + (6 × 3).
- Step 3: Solve the simpler problems: 120 + 18.
- Step 4: Add the results to get the final answer: 138.
3. What is the formula for the distributive property?
The formula for the distributive property explains how multiplication can be distributed across addition or subtraction. There are two main forms:
- Distributive Property of Multiplication over Addition: The formula is a × (b + c) = (a × b) + (a × c).
- Distributive Property of Multiplication over Subtraction: The formula is a × (b - c) = (a × b) - (a × c).
4. What is an example of multiplication in parts?
An excellent example of multiplication in parts is calculating 48 × 5. Instead of direct multiplication, you can use the break apart multiplication strategy by expressing 48 as (40 + 8).
The problem then becomes: (5 × 40) + (5 × 8).
This simplifies to 200 + 40, giving a final answer of 240. This method is especially useful for multiplying 2-digit numbers mentally.
5. How can I use this Grade 6 Maths worksheet at home?

6. Does this 'Multiplication in Parts' worksheet include an answer key?
Yes, this printable maths worksheet on multiplication in parts includes a detailed answer key with worked-out solutions. The answer key allows students to self-check their work and understand the step-by-step process, which is essential for effective learning and homework help.
7. Is this worksheet on the distributive property printable?
Absolutely. This worksheet on the distributive property is available as a free, printable PDF. You can easily download the file to your computer or mobile device and print it for classroom activities, homework, or extra practice at home.
8. What key skills does this worksheet on distributive property help build?
This worksheet is designed to build several crucial mathematical skills for Grade 6 students. Key skills include:
- Mental Math Multiplication: It teaches strategies to solve problems without a calculator.
- Number Sense: It improves the understanding of place value by breaking numbers apart.
- Problem-Solving Strategies: It provides a systematic approach to tackle multiplying large numbers.
- Algebraic Foundation: Mastering the distributive law is essential for success in future algebra topics.
9. How does this worksheet help with mental math multiplication?
This worksheet directly improves mental math multiplication skills by teaching students to use the distributive property to simplify problems. For instance, calculating 99 × 8 becomes easier by thinking of it as (100 - 1) × 8, which is (8 × 100) - (8 × 1) or 800 - 8 = 792. Regular practice with these multiplication tricks builds speed and accuracy.
10. What is the difference between the distributive property over addition and subtraction?
The primary difference between using the distributive property over addition versus subtraction is the final operation performed.
- Over Addition: You break a number into a sum (e.g., 52 = 50 + 2) and add the partial products at the end.
- Over Subtraction: You express a number as a difference (e.g., 49 = 50 - 1) and subtract the partial products at the end.
