$(4 \cdot 5)\cdot 3 = \underline{4} \cdot(5 \cdot \underline{3})$

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: $(4 \cdot 5)\cdot 3 = 4 \cdot(5 \cdot 3)$
