Answer :
To round numbers to the nearest 10,000, you need to look at the thousands digit of the number. If the number in the thousands place is 5 or greater, you round up. If it's less than 5, you round down. Let's go through each number step by step:
56,145: The digit in the thousands place is 6. Since 6 is greater than 5, we round up to 60,000.
23,109: The digit in the thousands place is 3. Since 3 is less than 5, we round down to 20,000.
47,178: The digit in the thousands place is 7. Since 7 is greater than 5, we round up to 50,000.
20,178: The digit in the thousands place is 0. Since 0 is less than 5, we round down to 20,000.
32,143: The digit in the thousands place is 2. Since 2 is less than 5, we round down to 30,000.
This rounding process makes it easier to work with large numbers, especially when estimating or making quick calculations.
