Round 15,680 to the nearest thousand

To round to the nearest thousand, we check the digit in the hundreds place. If it is less than 5, we round down, else we round up to the next thousand.

In this case, the digit in the hundreds place is "6" and "6" is 5 or more, so we round up to the next thousand.

15 680 ≈ 16 000

The nearest thousand is 16,000
