To find the least and greatest possible original numbers when the rounded place is in the tens and the rounded number is 460, we need to consider the numbers within the range of the tens place.

Let's start with the least number. Since the rounded place is in the tens, the original number could have been rounded down from the tens place. The digit in the ones place can be any number from 0 to 9.

Therefore, the least possible original number is 450, as when rounded, it becomes 460.

Now let's find the greatest possible original number. Again, the rounded place is in the tens. The digit in the ones place can be any number from 0 to 9.

Therefore, the greatest possible original number is 469, as when rounded, it becomes 460.

In summary, the least possible original number is 450, and the greatest possible original number is 469.
