Rewriting Problems with Rational Numbers Using Properties of Multiplication and Division

This lesson teaches how to rewrite problems involving rational numbers using the commutative and associative properties of multiplication and division. It reviews these properties, emphasizing that they apply only to addition and multiplication, not subtraction or division. Two examples demonstrate how to apply these properties to solve problems, including changing the order and grouping of numbers. The lesson concludes with a summary of the key concepts learned.

What is the commutative property in multiplication?

Explain the associative property and provide an example.

How can you rewrite a division problem using multiplication?

Describe how to use the commutative property to change the order of multiplication.

What happens when you change the grouping in multiplication?
