Answer: 270,000
Explanation:
When rounding to the nearest ten thousand we look at the ten thousand column, that number is 7 also repersenting 70,000. Next we look at the right of 7 to round (in other words looking at the thousands column which is 1=1000). If the number is less than 5 (0-4), the number stays the same, but if it is greater than 5 (5-9), we move it to the next number. Since 1 is less than 5 we round up, so therefore 271,403 rounded to the nearest ten thousand is 270,000.
