Explicație pas cu pas:
A = 7 km + 3 hm
7 km = 7 × 1000 m = 7000 m
3 hm = 3 × 100 m = 300 m
B = 10 dam + 2 dm
10 dam = 10 × 10 m = 100 m
2 dm = 2 : 10 m = 0,2 m
C = 5 dm + 62 cm
5 dm = 5 : 10 m = 0,5 m
62 cm = 62 : 100 m = 0,62 m
D = 123 cm + 5 mm
123 cm = 123 : 100 m = 1,23 m
5 mm = 5 : 1000 m = 0,005 m
E = 2,3 hm + 53 dam
2,3 hm = 2,3 × 100 m = 230 m
53 dam = 53 × 10 m = 530 m
F = 93 dam + 6 cm
93 dam = 93 × 10 m = 930 m
6 cm = 6 : 100 m = 0,06 m
G = 12 hm + 75 mm
12 hm = 12 × 100 m = 1200 m
75 mm = 75 : 1000 m = 0,075 m
H = 1 dm + 7 mm
1 dm = 1 : 10 m = 0,1 m
7 mm = 7 : 1000 m = 0,007 m
J = 3 dm + 4 cm
3 dm = 3 : 10 m = 0,3 m
4 cm = 4 : 100 m = 0,04 m
K = 10 km + 11 hm
10 km = 10 × 1000 m = 10000 m
11 hm = 11 × 100 m = 1100 m
L = 123 dm + 4 cm
123 dm = 123 : 10 m = 12,3 m
4 cm = 4 : 100 m = 0,04 m
