Example Question #1 : Apply Properties Of Operations As Strategies To Multiply And Divide: Ccss.Math.Content.3.Oa.B.5

Using the commutative property, if $6\times4=24$ what else is known?

Possible Answers:

$3\times8=24$

$4\times6=24$

$2\times12=24$

$12\times2=24$

$8\times3=24$

Correct answer:

$4\times6=24$

Explanation:

The commutative property of multiplication says that we can multiply numbers in any order and our product, or answer, will be the same.

Though all of our answer choices do equal , we started with $6\times4$ so our answer must use those numbers, but in a different order.

$6\times4=24$ and $4\times6=24$ demonstrates the commutative property of multiplication.
