• A. $(4\times 5)\times 3$
• B. $4\times (5\times 3)$
• C. $5\times (4\times 3)$
• D. $3\times (4\times 5)$

Answer 1

Answer: (A), (B), (C), (D)

$3\times (4\times 5)$

The product of the given expression is $4\times 5\times 3=60$
Let's apply the associative property for the above expression

The associative property of multiplication states that grouping of number does not affects the product of numbers.

1) The product of the expression $=(4\times 5)\times 3=60$
Hence, option a is correct.

2) The product of the expression $=4\times (5\times 3)=60$
Hence, option b is correct.

3) The product of the expression $=5\times (4\times 3)=60$
Hence, option c is correct.

4) The product of the expression $=3\times (4\times 5)=40$
Hence, option d is correct.

$\therefore$ All the given options are correct
