Applying the Commutative Property of Multiplication

This video tutorial explains the commutative property of multiplication, which allows numbers to be multiplied in any order without affecting the result. The lesson includes examples with fractions and decimals, demonstrating that changing the order of multiplication does not alter the outcome. The tutorial emphasizes that this property applies to both positive and negative numbers, reinforcing the concept with practical examples.

What does the commutative property of multiplication state?

• Multiplication can only be done with whole numbers.

• The order of numbers in multiplication affects the result.

• The order of numbers in multiplication does not affect the result.

• Multiplication must always be done from left to right.

When multiplying two fractions, what does the commutative property allow you to do?

• Change the order of multiplication without changing the result.

• Multiply only the numerators.

• Multiply only the denominators.

• Add the fractions instead of multiplying.

In the example of multiplying fractions, what is the result of -4/7 times 2/5?

• 10/35

• -10/35

• 8/35

• -8/35

How does the commutative property affect the multiplication of negative decimals?

• It makes the result unpredictable.

• It does not change the result, which remains positive.

• It changes the result to zero.

• It changes the result to a negative number.

What is the result of multiplying -3.2 by -2.5 using the commutative property?

• -8

• 0

• 8

• -6
