Answer: Largest = 404999
Smallest = 395,000.
Explanation:
Given data:
Number of people in attendance = 400,000
Solution:
If we were to round off to the nearest ten thousand the greatest number we can get would be = 404999.
And following the same principle the smallest number we would be able to get would be = 395000
Therefore, the largest number of people who could have attended the inauguration would be 404999.
And the smallest number of people who could have attended would be 395000.
