A) 1
B) 2
C) 3
D) 4

Answer 1

To find the missing number in the number sentence (7 × 4) × 6 = 7 × ( __ × 6), we need to use the associative property of multiplication. The missing number is 4, so the correct answer is D) 4.

Step-by-step explanation:

To find the missing number in the number sentence (7 × 4) × 6 = 7 × ( __ × 6), we need to use the associative property of multiplication. According to this property, changing the grouping of factors does not change their product.

Thus, we can rewrite the equation as (7 × 4) × 6 = 7 × 6 × __.

Now we can solve for the missing number by dividing both sides of the equation by 6. This gives us (7 × 4) = 7 × __.

We can see that the missing number is 4, so the correct answer is D) 4.
