Odpowiedź:
a) 3cm 7mm = 3 7/10cm (1mm = 1/10cm)
b) 12m 19cm = 12 19/100m (1cm = 1/100m)
c) 7km 380m = 7 380/1000km = 7 19/50km (1m = 1/1000km)
d) 4kg 350g = 4 350/1000kg = 4 7/20kg (1g = 1/1000kg)
e) 9kg 17dag = 9 17/100kg (1dag = 1/100kg)
f) 5t 75kg = 5 75/1000t = 5 3/40 (1kg = 1/1000t)
Mam nadzieje, że pomogłam :)
