Find the least and greatest possible original numbers:

ROUNDED PLACE is Thousands,
ROUNDED NUMBER is 1,800.
What is the Least number and the Greatest number?

1,500 to 2,499

To find the least and greatest possible original numbers, we need to consider the range of values given the rounded place (thousands) and the rounded number (1,800).

The rounded place is thousands, which means that the original number could have been rounded to any value in the range of 1,750 to 1,850, since any number in this range, when rounded to the nearest thousands, would be rounded to 1,800.

To find the least possible original number, we would take the lower end of the range, which is 1,750. This means that the least possible original number that, when rounded to the nearest thousands, would be 1,800 is 1,750.

To find the greatest possible original number, we would take the higher end of the range, which is 1,850. This means that the greatest possible original number that, when rounded to the nearest thousands, would be 1,800 is 1,850.

Therefore, the least possible original number is 1,750 and the greatest possible original number is 1,850.
