Answer :

To round 159,746 to the nearest thousand, follow these steps:

1. Identify the thousands place: In the number 159,746, the digit in the thousands place is 9 (thousands), since the number reads 159,746.

2. Look at the digit to the right: The digit immediately to the right of the thousands place is the hundreds place. In 159,746, this digit is 7 (hundreds).

3. Apply the rounding rule:
- If the hundreds digit is 5 or greater, you round up the thousands digit.
- If the hundreds digit is less than 5, you keep the thousands digit the same.

In this case, since the hundreds digit is 7, which is greater than 5, you round up.

4. Round the number:
- Increase the thousands digit by 1: 9 becomes 10.
- When the thousands digit rolls over from 9 to 10, it increases the tens of thousands digit by 1.
- Thus, 159,746 rounded to the nearest thousand becomes 160,000.

So, the number 159,746 rounded to the nearest thousand is 160,000.
