✔ 最佳答案
100cm = 1m
1000m = 1km
So, 300,000cm/100 = 3,000m
3,000m/1000 = 3km

100cm=1m
1000cm=10m
10000cm=100m
100000cm=1000m
1000m=1km
100000cm=1km
so:300000cm=3km

300000cm=3000m=3km

300000cm = (300000/100) m = 3000m (因為 1m = 100cm)
3000m = (3000/1000) km = 3km (因為 1km = 1000m)
所以, 最後答案是 300000cm = 3km

如果你唔想自己慢慢計, 可以上以下網:http://www.mold.net.tw/classroom/unit.htm網裡面, 你見到所謂公分, 即是cm

唔好意思,睇錯題首先要搵出300000cm=幾多m100cm=1m所以300000除100=3000m(1km=1000cm)3000除1000=3km答案:3km
2007-12-30 8:05 pm
1cm=1000km

300000/1000=300km
