mình ko chắc có đúng ko ???
Số?
a) 7 dm = ? cm 8 m = ? dm 9 m = ? cm
60 cm = ? dm 600 cm = ? m 50 dm = ? m
b) 1 km = ? m 1 000 m = ? km
a) 7 dm = 7 x 10 = 70(cm)
8 m = 8 x 10 = 80(cm)
9 m = 9 x 100 = 900(cm)
60 cm = 60 : 10 = 6(dm)
600 cm = 600 : 100 = 6(m)
50 dm = 50 : 10 = 5(m)
b) 1 km = 1 x 1000 = 1000(m)
1000 m = 1000 : 1000 = 1(km)
