Transforma 720dam=--hm, 3500m=--…dam , 200cm=--dm, 30hm=--km, 150dm=--cm, 389dam=--m, 8000mm=--dm, 700m=--hm, 4100dm=--dam, 92hm=--m, 660m=--cm, 70km=--dam, 9000m=--dam, 4200m=--km, 510000mm=--m,820hm=--dm, 69dam=--cm, 40k. =--m

Answer 1

720 dam = 72 hm
3500 m = 350 dam
200 cm = 20 dm
30 hm =3 km
150 dm =1500 cm
389 dam = 3890 m
8000 mm = 80 dm 
700 m =7 hm
4100 dm = 41 dam
92 hm = 9200 m
660 m = 66000 cm 
70 km = 7000 dam 
9000 m = 900 dam 
4200 m = 4,2 km
510000 mm = 510 m 
820 hm = 820000 dm 
69 dam = 69000 cm 
40 km = 40000 m
Sper ca te-am ajutat COROANA!!
