Final answer:
To round 15,327 to the nearest ten thousand, you look at the thousands digit (5), and since it is 5 or greater, round up the ten thousand digit to 2, resulting in 20,000.
Step-by-step explanation:
To round 15,327 to the nearest ten thousand, we must look at the digit in the ten thousand places, which is 1. To decide how to round it, we need to consider the digit in the thousands place, which is 5. Since 5 equals or exceeds 5, we round up the ten thousand place to 2, resulting in 20,000 as our rounded number to the nearest ten thousand. If the digit in the thousands place had been less than 5, we would have rounded down, keeping the ten thousand place as it was.
