Final answer:
To round the number 316,483 to the nearest ten, we look at the tens and ones place digits. The ones place has a '3', so the tens place '8' remains unchanged. The rounded number is 316,480.
Step-by-step explanation:
The student has asked to round the number 316,483 to the nearest ten. To do this, we need to look at the digit in the tens place and the digit to its immediate right, which is the ones place. In the number 316,483, the tens place is occupied by an '8' and the ones place by a '3'. If the ones place is 5 or higher, we round the tens place up. If it's 4 or lower, we keep the tens place as it is.
Since the digit in the ones place is '3', we do not round up the '8' in the tens place. Therefore, the number 316,483 rounded to the nearest ten is 316,480, which corresponds to option (a).
