Question

Match the following numbers with the numbers rounded off to the nearest 1000.

• A. 39,000
• B. 40,000
• C. 38,000

Answer 1

Always look at the digit at the hundreds place!
If more than or equal to 5, round up to the next thousand.
If less than 5, round down to the previous thousand.

1. 38,290 --> 38,000
Since 2 < 5, round down to the nearest thousand.
38,290 rounded off to the nearest 1000 is 38,000.

2. 38,510 --> 39,000
Since 5 = 5, round up to the nearest thousand.
38,510 rounded off to the nearest 1000 is 39,000.

3. 39,890 --> 40,000
Since 8 > 5, To round up to the nearest 1000, we add 1 to the digit in the thousands place.
⇒ 9 + 1 = 10
Writing 0 in the thousands place, add 1 to the digit in the ten thousands place.
⇒ 3 + 1 = 4
39,890 rounded off to the nearest 1000 is 40,000.
