A shopping channel shipped 467,023 packages last year. What is a reasonable estimate of the number of packages shipped?

The number is 470, 000

To explain further:

An example is

14,494

To round off the height value to the nearest thousand we can use the expanded from to clarity the position of numbers which is:

10, 000 = ten thousand

4, 000 = thousands

400 = hundreds

90 = tens

4 = ones

Here we can notice than four thousand is the value where the nearest thousands is placed. Hence we can round off the number of 14, 494 into 14, 000. Notice 0-4 rounding off rules.
