1. 12*1/5 = 2400 gramow = 2,4kg
2. 1mm = 1/10 cm
7mm = 7/10 cm
15mm = 15/10 cm
1 cm = 1/100 m
41 cm = 41/100 m
107 cm = 107/100 m
1 m = 1/1000 km
560m = 560/1000 km
2358 m = 2358/1000 km
1 g = 1/1000 kg
29 g = 29/1000 kg
4506 g = 4506/1000 kg
1 dag = 1/100 kg
38 dag = 38/100 kg
250 dag - 250/100 kg
1 kg = 1/1000 t
130 kg = 130/1000 t
2452 kg = 2452/1000 t
