Question

Answer 1

The smallest amount of people who could be there would be 750,000.  The largest would have been 849,999.

Answer 2

Answer:

The least whole number can be 750,000 and the greatest whole number can be 849,999.  

Step-by-step explanation:

Consider the provided information.

We need to find the least whole number that's rounds to 800,000 when rounding to the nearest hundred thousands,

Rule of rounding a number.

If the number on the right side of rounding digit is 0, 1, 2, 3, 4 then no need to change the rounding digit and change the rest of the digit right to rounding digit with 0.

If the number on the right side of rounding digit is 5, 6, 7, 8, 9 then rounding digit rounds up by one number  and change the rest of the digit right to rounding digit with 0.

Now, consider the number 800,000 .

We want the least number so the number at the hundred thousands place should be 7.

We want to increase the number at the hundred thousands place by 1 so the least possible choice for tens place is 5.

Hence, the least whole number can be 750,000.

Now we want the greatest whole number that's rounds to 800,000 .

Similarly, for greatest whole number the number should be greater than 800,000 . We don't want to increase the number at the hundred thousands  place so the greatest possible choice for ten thousands place is 4. To make the largest number put 9 at the rest places.

Hence, the greatest whole number can be 849,999.
