Tips for Understanding the Associative Property of Multiplication

Oct 13, 2025 by wbrum.org 100 views

The Associative Property of Multiplication is a fundamental concept in mathematics that helps us simplify complex multiplication problems. It states that when we multiply three numbers together, the order in which we multiply them does not change the result. In other words, the associative property allows us to regroup or rearrange the numbers being multiplied without affecting the final product.

What is the Associative Property of Multiplication?

The associative property of multiplication is often represented by the following equation:

(a × b) × c = a × (b × c)

This equation shows that the order in which we multiply the numbers a, b, and c does not change the result. For example, if we multiply 2, 3, and 4 together, we can do it in any order and still get the same result:

(2 × 3) × 4 = 2 × (3 × 4)

This property is essential in simplifying complex multiplication problems and making it easier to solve them.

Which of the Following Number Sentences Models the Associative Property of Multiplication?

Now, let's look at the given number sentences and determine which one models the associative property of multiplication.

A. $80 \times 5 = (40 \times 5) + (40 \times 5)$

This equation does not model the associative property of multiplication. The associative property states that the order in which we multiply the numbers does not change the result. However, in this equation, we are adding two products together, which is not the same as multiplying them together.

B. $(11 \times 6) \times 7 = 11 \times (6 \times 7)$

This equation models the associative property of multiplication. We can see that the order in which we multiply the numbers 11, 6, and 7 does not change the result. This is a perfect example of the associative property in action.

C. $3 \times (2 \times 4) = (3 \times 2) \times 4$

This equation also models the associative property of multiplication. We can see that the order in which we multiply the numbers 3, 2, and 4 does not change the result. This equation demonstrates the associative property in a different way.

Conclusion

In conclusion, the correct answer is B. $(11 \times 6) \times 7 = 11 \times (6 \times 7)$ . This equation models the associative property of multiplication, which states that the order in which we multiply three numbers together does not change the result.

Why is the Associative Property of Multiplication Important?

The associative property of multiplication is an essential concept in mathematics that helps us simplify complex multiplication problems. It allows us to regroup or rearrange the numbers being multiplied without affecting the final product. This property is used extensively in algebra, geometry, and other branches of mathematics.
