Answer
$(4 \cdot 5)\cdot 3 = \underline{4} \cdot(5 \cdot \underline{3})$
Work Step by Step
The associative property states that for any real numbers a, b, and c:
$a \cdot (b \cdot c) = (a \cdot b) \cdot c$
Thus, apply the associative property to the given problem to find:
$(4 \cdot 5)\cdot 3 = 4 \cdot(5 \cdot 3)$
