Explicație pas cu pas:
1dm = 10 cm; 1dam = 10 m; 1hm = 100 m; 1m = 100 cm
3,6 dm = 3,6*10 = 36 cm
a) 54/36 = 9/6 = 3/2
b) 2,4 dam = 2,4 * 10 = 24 m
24/90 = 12/45 = 4/15
c) 1,08 hm = 1,08*100 = 108 m
7200 cm = 72 m
108/72 = 54/36 = 9/6 = 3/2
d) 0,036 km = 0,036 * 1000 m = 36 m
540 dm = 540 * 10= 5400 cm = 54 m
36/54 = 6/9 = 2/3
