Question

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

• A. 1,89,000
• B. 1,90,000
• C. 1,87,000

Answer 1

If more than or equal to 5, round up to the next thousand.
If less than 5, round down to the previous thousand.

1. 1,87,490 ---> 1,87,000
Since 4 < 5,
1,87,490 rounded off to the nearest 1000 is 1,87,000.

2. 1,89,510 ---> 1,90,000
Since 5 = 5,
To round up to the nearest 1000, we add 1 to the digit in the hundreds place.
⇒ 9 + 1 = 10
Writing 0 in the thousands place, add 1 to the digit in the ten thousands place.
⇒ 8 + 1 = 9
1,89,510 rounded off to the nearest 1000 is 1,90,000.

3. 1,88,890 ---> 1,89,000
Since 8 > 5,
1,88,890 rounded off to the nearest 1000 is 1,89,000.
