Problem: Rounding Numbers to the Nearest Ten Thousand
The task is to round each given number to the nearest ten thousand. To do this, we follow these steps:
1. Identify the ten-thousands place: This is the digit four places from the right in a number.
2. Look at the digit in the thousands place: This is the digit immediately to the right of the ten-thousands place.
3. Apply the rounding rule:
- If the digit in the thousands place is 5 or greater, round up the ten-thousands digit by 1.
- If the digit in the thousands place is less than 5, keep the ten-thousands digit as it is.
4. Replace all digits to the right of the ten-thousands place with zeros.
Let's solve each problem step by step.
