Answer:
The largest possible number of overseas visitors would be 11,640,000.
The smallest possible number of overseas visitors would be 11,550,000.
Step-by-step explanation:
The number 11,600,000 was rounded off to the nearest 100,000.
This means that either 0 or 1 was added to the figure with place value of 100,000.
It would be zero (0) in the case where the number after the 100,000th placed value number is lower than 5 and it would be one (1) in the case where the number after the 100,000th placed value is greater than or equal to 5.
Therefore, the largest possible number of overseas visitors would be 11,640,000.
The smallest possible number of overseas visitors would be 11,550,000.
