If the 864 refers to meters, then it's already rounded to the nearest meter. If it refers to something else, you need to tell us what it is.
4.5 m
2.345 m = 234.5 cm rounds to 230 cm = 2.3 m
To round up 472.9 cm to the nearest meter, we first convert 472.9 cm to meters by dividing by 100 (since there are 100 centimeters in a meter). This gives us 4.729 meters. Rounding up to the nearest meter means we round up to 5 meters, as 4.729 is closer to 5 than it is to 4. Therefore, 472.9 cm rounded up to the nearest meter is 5 meters.
27 over 100. 27 cm = 27/100 of a meter (0.27 m). There are 100 centimeters (cm) in a meter (m).
2 m
If the 864 refers to meters, then it's already rounded to the nearest meter. If it refers to something else, you need to tell us what it is.
4 m
4.78 m to the nearest m is 5 m.
864 m = 0.864 kmTo convert from m to km, divide by 1000.
1 m = 100 cm so 864
85765.47944 m to the nearest metre is 85765 m since the tenths digit is less than 5 it rounds down. However: 85765.47944 CENTImetres *IS* 858 metres to the nearest metre. ie 85765.47944 cm to the nearest m: 100 cm = 1 m → 85765.47944 cm = 85765.47944 ÷ 100 m = 857.6547944 m → 858 m to the nearest metre as the tenths digit is 5 or more it rounds up.
4.5 m
6.42 m and 5.97 m( both to the nearest cm)
1 m = 100 cm so 5666 m = 566600 cm. Simple!
The centi- prefix means one hundredth → 1 cm = 1/100 m → 40 cm = 40 × 1/100 m = 0.4 m → 52 m 40 cm = 52 m + 0.4 m = 52.4 m
There are 100 cm in 1 meter, so 276 cm = 2.76 m, which rounded to the nearest metre is 3 metres.
