10 m = 10 metri
2, 4 dam = 2, 4 decametrii. 1 dam = 10 metri. => 2, 4 dam = 24 m
0, 3 ham = 0, 3 hectometrii 1 hm = 100 metrii => 0, 3 hm = 30 m
Per total.
10 m + 2, 4 dam + 0, 3 ham = 64 m
10 m + 24 m + 30 m = 64 m
Rezolvare : 10 m + 24 m + 30 m = 64 m
Pentru ca : 2, 4 dam = 24 m si 0, 3 ham = 30 m
