Final answer:
To find the missing factor in a multiplication problem when the product and one factor are known, divide the product by the known factor. In this case, the missing factor when the product is 72 and one factor is 6, is 12.
Step-by-step explanation:
The student is asking for a missing factor in a multiplication problem. In multiplication, if you know the product and one of the factors, you can find the missing factor by dividing the product by the known factor.
The product in this case is 72, and the known factor is 6. When we divide 72 by 6, we get 12. Hence, if the product is 72 and one factor is 6, the missing factor is 12. Hence the correct answer among the provided options would be D. 12.
