Question

1. associative property: solve and circle the shapes to model. (3×5)×4=3×(×4)

Explanation:

Step1: Recall the associative property of multiplication

The associative property of multiplication states that \((a\times b)\times c=a\times(b\times c)\).
In the given equation \((3\times5)\times4 = 3\times(\square\times4)\), comparing with the formula \(a = 3\), \(b = 5\), \(c=4\).

Step2: Find the missing number

According to the associative property of multiplication, the missing number is \(5\).

Answer:

\(5\)
