Pozdrawiam! :)

I mała podpowiedź:

1 kg = 100 dag = 1000 g

1 km = 1000m = 100000cm = 1000000 mm

1 cm = 10 mm 

:)

Answer 2

151cm=1 m 51 cm = 1,51 m

423cm=4m 23 cm = 4,23 m

 

3405 m = 3km 405 cm = 3,405 km

7421m = 7 km 421m = 7,421 km

 

895dag = 8 kg 95 dag = 8,95 kg

142 dag = 1 kg 42 dag = 1,42 kg

 

94 mm = 9 cm 4 mm = 9,4 cm

125 mm = 12 cm 5 mm = 12,5 cm

 

AB = 4 cm 7 mm

AB= 47 mm

AB = 4,7 cm
