There are 100 cm in 1 meter, so 276 cm = 2.76 m, which rounded to the nearest metre is 3 metres.
3.5 rounded to the nearest cm is 4cm
It is: 7 metres because 71 cm is greater than 50 cm
There's 100 cm on 1 meter, so the nearest meter would be 5 meter. (500 cm)
Round it to the nearest metre by rounding it to the nearest 100 cm, then if you rounded down add 100 cm otherwise you rounded up and so subtract 100 cm to get to the farthest metre. eg 125 cm to the farthest metre: To the nearest metre 125 cm rounds down to 100 cm. Thus to the farthest metre, as rounded down add 100 cm to give 200 cm to the farthest metre.
