Question

Multiplica o divide para resolver las siguientes reducciones 6km a m 38 dan a m 87m a dam 20hm a m 62km a dm

Answer 1

Hola,

6 km = 6 000 metros

38 dam = 380 metros

87 m = 8, 7 dam  (o 8 dam y 7 m )

20 hm = 2 000 metros

62 km = 620 000 dm

Answer 2

a) 64 km a m = 64 × 1000 = 64000 m
b) 38 dam(Dm) a m = 38 × 10 = 380 m
c) 87 m a dam(Dm) = 87 ÷ 10 = 8,7 dam(Dm)
d) 20Hm a m = 20 × 100 = 2000 m
e) 62 Km a dm = 62 × 10000 = 620000 dm
