Question #449f9

Answer 1

2,120,000

Explanation:

2,123,945 rounded off to 10,000 will be 2,120,000 because when we are rounding off, we see by which number we are rounding off(here 10,000), and see how many 0's are in the rounding off number.
here there are four 0's, so we'll see the last four numbers of the number we are rounding off(that are 3945).

Answer 2

`2,123,945` will round to `2,120,000`

Explanation:

The phrase ' to the nearest' means that the rounded answer will be a multiple of the given level of accuracy.

'To the nearest `100`' means the answer will be a multiple of `100` and will be a number ending in `100, 200, 300, 400 ...`etc

'To the nearest `20`' means the answer will be a multiple of `20` and will be a number ending in `20, 40, 60, 80, 00`

'To the nearest `10'000`' means the answer will be a multiple of `10,000` and will be a number ending with `4` zero's.

To decide which `10,000` is 'nearer', look at the digit in the thousands place (4th digit from the right).

In this case :
`3,000` is closer to `color(blue)(0)" "` (only `3,000` more) than to
`10,000" (which is "7,000` more)

(if the next digit is `5` or more, round up, if `4` or less, round down)

`2,12color(blue)(3),945` will round to `2,12color(blue)(0),000`

`2,120,000` is the nearest multiple of `10,000`
