IncorrectStep-by-step walkthrough
Choose a solution method
Method #1Direct ApproachStep 1: Identify the target place value
We need to round 47,318 to the nearest thousand. The thousands digit is 7 (in 47,318).
Step 2: Look at the digit to the right
The digit immediately to the right of the thousands place is 3 (in 47,318).
Step 3: Apply the rounding rule
Since , we round down — keep the thousands digit as 7 and replace the remaining digits with zeros.
Step 4: Write the rounded answer
Method #2Process of EliminationStep 1: Identify what is being asked
We need to round 47,318 to the nearest thousand, so our answer must be a multiple of 1,000.
Step 2: Eliminate 47,300
47,300 is rounded to the nearest hundred, not the nearest thousand. This is the wrong level of rounding.
Step 3: Eliminate 50,000
50,000 would only be correct if we rounded to the nearest ten thousand. 47,318 is much closer to 47,000 than to 50,000.
Step 4: Eliminate 48,000
48,000 would require rounding up. We only round up when the digit to the right of thousands is 5 or more. Here it is 3, so we round down.
Step 5: Select the correct answer
47,000 is correct — the digit after the thousands place is 3, which means we round down, giving .
