Final answer:
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.
