Round each of the following numbers to the nearest thousand :

(i) 7,386

(ii) 34,276

(iii) 23,804

(iv) 76,540

(i) 7,386

The hundreds digit is 3. Since 3 is less than 5, we round down.

The thousands digit (7) remains the same, and the hundreds, tens, and units digits become 000.

Hence, number rounded to the nearest thousand = 7,000.

(ii) 34,276

The hundreds digit is 2. Since 2 is less than 5, we round down.

The thousands digit (4) remains the same, and the hundreds, tens, and units digits become 000.

Hence, number rounded to the nearest thousand = 34,000.

(iii) 23,804

The hundreds digit is 8. Since 8 is 5 or greater, we round up the thousands digit.

The thousands digit (3) becomes 4, and the hundreds, tens, and units digits become 000.

Hence, number rounded to the nearest thousand = 24,000.

(iv) 76,540

The hundreds digit is 5. Since 5 is 5 or greater, we round up the thousands digit.

The thousands digit (6) becomes 7, and the hundreds, tens, and units digits become 000.

Hence, number rounded to the nearest thousand = 77,000.
