Explicație pas cu pas:
a) 400km = 400 × 1000m = 400000m
5000mm = 5000:1000= 5m
60dm= 60 × 10= 600cm
b)30kg = 30 × 1000 = 30000g
70000kg = 70000:1000 = 70t.
480000g = 480000:1000=480kg => 480kg=480000g
c) 200 lei = 20000 bani
800000 bani = 800 lei
4325 bani = 43 lei 25 bani => 43 lei 25 bani = 4325 bani
