Question

Which expression represents the associative property of multiplication?

Answer 1

The associative property of multiplication states that the way in which numbers are grouped in a multiplication problem does not change the product.

$(A\times B)\times C=A\times (B\times C)$

Finding the product of $A$ and $B$ and then multiplying the product by $C$ is the same as multiplying $A$ by the product of $B$ and $C.$

$\therefore (15\times 12)\times 3=15\times (12\times 3)$ is the correct answer.
