Descompón
cada medida usando el mayor número de unidades posible. Pg 71.
56 m =
50 m + 6
m = 5 dam + 6 m
72 m =
70 m + 2
m = 7 dam + 2 m
64 m =
60 m + 4 m
= 6 dam + 4 m
89 m =
80 m + 9
m = 8 dam + 9 m
278 m = 200 m + 70 m + 8 m = 2 hm + 7 dam + 8 m
698 m
= 600 m +
90 m + 8 m = 6 hm + 9 dam + 8 m
583 m =
500 m +
80 m + 3 m = 5 hm + 8 dam + 3 m
810 m
= 800 m +
10 m = 8 hm + 1 dam
1.367 m = 1.000 m + 300 m + 60 m + 7 m = 1 km + 3 hm + 6 dam
+ 7 m
5.309 m = 5.000 m + 300 m + 9 m = 5 km + 3 hm + 9 m
2.876 m = 2.000 m + 800 m + 70 m + 6 m = 2 km + 8 hm + 7 dam
+ 6m
7.012 m = 7.000 m + 10 m + 2 m = 7 km + 1 dam + 2 m
