Answer
(i) 925
The tens digit is 2. Since 2 is less than 5, we round down.
The hundreds digit (9) remains the same, and the tens and units digits become 00.
Hence, number rounded to the nearest hundred = 900.
(ii) 6,854
The tens digit is 5. Since 5 is 5 or greater, we round up the hundreds digit.
The hundreds digit (8) becomes 9, and the tens and units digits become 00.
Hence, number rounded to the nearest hundred = 6,900.
(iii) 41,263
The tens digit is 6. Since 6 is 5 or greater, we round up the hundreds digit.
The hundreds digit (2) becomes 3, and the tens and units digits become 00.
Hence, number rounded to the nearest hundred = 41,300.
(iv) 27,861
The tens digit is 6. Since 6 is 5 or greater, we round up the hundreds digit.
The hundreds digit (8) becomes 9, and the tens and units digits become 00.
Hence, number rounded to the nearest hundred = 27,900.
(v) 5,549
The tens digit is 4. Since 4 is less than 5, we round down.
