1. The problem is to round the number 79955 to the nearest thousand. 2. Identify the digit in the thousands place: in 79955, the thousands digit is 9 (the third digit from the right). 3. Look at the digit in the place immediately to the right of the thousands place, which is the hundreds place here. This digit is 9. 4. If the hundreds digit is 5 or more, round up the thousands digit by 1; if less than 5, keep the thousands digit the same. 5. Since the hundreds digit is 9 (which is greater than 5), round up. 6. Increase the thousands digit from 9 to 10, which means the number rounds up from 79,000 to 80,000. 7. Therefore, 79955 rounded to the nearest thousand is 80000.
