Answer 1

Answer: B

Step-by-step explanation:

The way to find an average of two numbers is to add them then divide the sum by two. Since the smaller and larger number add up to 19,992,000, the sum of the two numbers is always going to be 19,992,000. Because we know this, we can do the next step in finding the average: dividing by 2. 19,992,000/2=9,996,000. Therefore, the answer will be B
