Answer 1

a) 70 1/20m = 1401/20 *100cm= 140100/20cm= 7005 cm

b) 137 cm =137:10dm =  13, 7 dm

30,1 cm =30,1:10dm =  3,01dm

0,85m = 0,85 m*100cm = 85 cm :10dm = 8,5 dm

0,012 km = 0,012*1000m=12m*100cm=1200:10dm=120dm

3/8 km = 3/8 km *1000m = 3000/8 m = 375 m *100cm =37500cm:10dm = 3750 dm

c) 5000cm = 5000cm:10 dm = 500 cm

20000cm = 20000:10 dm = 2000dm

1500000mm = 1500000:10cm= 150000cm :10 dm = 15000dm

70000000 mm = 70000000:10cm=7000000:10dm=700000dm

d)250000cm = 250000 :100m =2500m : 1000km = 2,5 km

75000cm =75000cm :100m = 750 m :1000 km = 0,75 km

200000000cm= 200000000 : 100 m = 2000000m : 1000km = 2000 km

25000000mm = 25000000:10cm = 2500000cm:100m = 25000m :1000km = 25 km

e) 650 g = 650g: 1000 kg = 0,65 kg

1520 g =1520 g : 1000 kg = 1,52 kg

360 dag = 360 dag * 10 g = 3600g :1000kg = 3,6 kg

16,5 t = 16,5 t * 1000kg = 165 00 kg

10 1/5 t = 51/5 t *1000kg = 51000/5 kg = 10200 kg

f) 12kg = 12kg *1000g = 12000g :10 dag = 1200 dkg

6,75 kg = 6,75 kg *1000g = 6750 g : 10dag = 675 dkg

0,08 t = 0,08 t * 1000kg =  80 kg *1000g = 80000g : 10 dag = 8000 dag

750 g = 750g :10 dag = 75 dag

9g = 9g :10 dag = 0,9 dag

g) 1200 mg = 1200 mg : 1000g = 1,2 g

70 mg = 70 mg : 1000g =  0.07 g

6 dag = 6 dag * 10 g = 60 g * 1000mg = 60000 mg : 1000g = 60 g

7,2 dag = 7,2 dag * 10g = 72 g * 1000 mg = 72000 mg: 1000g  = 72 g

0,6 kg = 0,6 * 1000g = 600 g * 1000 mg = 600000mg : 1000g = 600 g
