Question

Transformati in decametri:
a) 50m; 8hm; 10,3km; 40 000mm; 800 cm; 750 dm;
b) 24 500 mm; 7,3 hm; 2,07 m; 0,05 km; 160 702 cm; 21 712 dm;
c) 250,4 cm; 1,3 dam; 1,8 hm; 40 237 mm; 97,5 dm; 13 km.

Answer 1

a)50m=5 decametri;8hm=80decam;10,3km=10300decam;40000mm=4decam;
800cm=0,8 decam; 750dm=7,5 decam;
b)24500mm=2,45 decam;7,3hm=73 decam;2,07m=0,207 dam;0,05=5dam;160702 cm=160,702 dam; 21712dm=217,12 dam;
c)250,4 cm=0,2504 dam;1,3dam=1,3dam;1,8hm=18dam;40237mm=40,237dam;97,5dm=0,975 dam;13 km=1300dam;
In principiu unitatile de masura pana la clasa a 8-a sunt in ordine: mm,cm,dm,m,dam,hm,km. fiecare unitate de masura e 10 unitati de masura mai mici.De exemplu 1 km= 10 hm sau 1 dm=10 cm.Din asta rezulta ca fiecare unitate de masura e 0,1 din unitatea mai mare.Exemplue 1m=0,1dam
