  1. Giải đáp:
    315 cm = 3,15 m
    3 km 245 = 3,245 km
    386 cm = 3,86 m
    197 m = 0,197 km
    14 m 7 cm = 14,07 m
    246 cm = 2,46 m
    34 dm = 3,4 m
    5 km 24 m = 5, 024 km
    3 km 245 = 3,245 km

  2. Giải đáp:
    315cm= 3,15 m
    3km245m= 3,245 km
    386cm= 3,86 m
    197m= 0,197 km
    14m7cm= 14,07 m
    246cm= 2,46 m
    34dm= 3,4 m
    5km34m= 5,034 km
    3km245m= 3,245 km
    Lời giải và giải thích chi tiết:
    Ta có:
    – 1km = 10hm = 100dam = 1000m = 10000dm = 100000cm = 1000000mm
    – 1hm = 10dam = 100m = 1000dm = 10000cm = 100000mm
    – 1dam = 10m = 100dm = 1000cm = 10000mm
    – 1m = 10dm = 100cm = 1000mm
    – 1dm = 10cm = 100mm
    – 1cm = 10mm
