800 cm = ........... dm 400 m = ........... dm 60 dm = ........ cm 700 dm = .......... m 64 km = ... ....... m pake cara ya :)

800 cm = 800/10 = 80 dm
400 m = 400 x 10 = 4000 dm
60 dm = 60 x 10 = 600 cm
700 dm = 700/10 = 70 m
64 km = 64 x 1000 = 64000 m

cm ke dmnaik 1 jdi bagi 10
800:10=80dm
m ke dm turun 1 dikali 10
400x10=4000dm
dm ke cm turun 1 dikali 10
60x10=600cm
dm ke m naik 1 dibagi 10
700:10=70m
km ke m turun 3 dikali 1000
64x1000=64m
