Answer:To round a number to the nearest thousand, look at the hundreds digit. If it's 5 or greater, round the thousands digit up. If it's 4 or less, keep the thousands digit the same. Step-by-step explanation:For example: • 7,434 rounded to the nearest thousand is 7,000 because the hundreds digit (4) is less than 5.• 9,981 rounded to the nearest thousand is 10,000 because the hundreds digit (9) is 5 or greater.• 12,678 rounded to the nearest thousand is 13,000 because the hundreds digit (6) is 5 or greater.
