Question

In one year, the McAlister family drove their car 15,680 miles. To the nearest thousand, how many miles did they drive their car that year?

Answer 1

The answer is 16,000

Answer 2

16,000 miles.
You need to round up from the hundreds.
As a rule of thumb, if the number after the number you're rounding is above 5, round up; if not, round down.
Like if I was rounding to tens:
38 rounds up to 40
34 rounds down to 30.
Anyways, in this case, then, we round 15680 up to 16000 miles.
