Final answer:
To round 653,500 to the nearest thousand, we look at the digit in the ones place (0), and since it is 0, we round down to the nearest thousand, resulting in 653,000.
Step-by-step explanation:
To round 653,500 to the nearest thousand, we need to look at the digit in the ones place (0 in this case). If the digit in the ones place is 0, 1, 2, 3, or 4, we round down to the nearest thousand. If the digit in the ones place is 5, 6, 7, 8, or 9, we round up to the nearest thousand. In this case, the digit in the ones place is 0, so we round down. Since the thousands place is already 653, we leave it as it is and the final rounded number is 653,000.
