minh nha
Trả lời:
1000m = 1 km.
10 000 000m = 10 000 km
Hok tốt !

câu3
49cm+82m= 44m+1cm= 22m+22m+22m=
câu 1 :
1km = 100000cm 1000m = 1km 60cm = 6dm
9m = 90dm 400 cm = 4m 1dm = 0,1m
8km = 8000m 5dm = 50cm 9000m = 9km
câu 2 :
458 + 123 =581 569 + 569 = 1138 642 + 123 = 765
câu 3 : bạn ơi câu 3 thì đề bài ng ta cho kết qua ra là đơn vị j vậy ạ?
câu 1 :
1km = 100000cm 1000m = 1km 60cm = 6dm
9m = 90dm 400 cm = 4m 1dm = 0,1m
8km = 8000m 5dm = 50cm 9000m = 9km
câu 2 :
458 + 123 =581 569 + 569 = 1138 642 + 123 = 765
câu 3
49cm + 82m 8249
44m +1m =44,01 m
22m+22m+22m= 66m
