Question

fill in the blanks. then, choose the property of multiplication you used. (a) \\(\square \times 1 = 5\\) select (b) \\(0 \times 9 = \square\\) select (c) \\(\square \times 9 = 9 \times 7\\) select (d) \\(2 \times (5 \times 9) = (2 \times 5) \times \square\\) select

Explanation:

Part (a)

Step 1: Recall the identity property of multiplication.

The identity property of multiplication states that any number multiplied by 1 gives the number itself. So, if \( \square \times 1 = 5 \), then the number in the square should be 5 because \( 5\times1 = 5 \).

Step 1: Recall the zero property of multiplication.

The zero property of multiplication states that any number multiplied by 0 is 0. So, \( 0\times9 = 0 \).

Step 1: Recall the commutative property of multiplication.

The commutative property of multiplication states that \( a\times b=b\times a \). So, if \( \square\times9 = 9\times7 \), by the commutative property, the number in the square should be 7 because \( 7\times9 = 9\times7 \).

Answer:

5
