Answer 1

1.
a) 20 mm = 2 cm
    60 mm = 6 cm
    300 mm = 30 cm
    670 mm = 67 cm
b) 4 dm = 40 cm
   20 dm = 200 cm
 5 dm = 50 cm
 3 dm = 30 cm
7 dm = 70 cm
 4 dm = 40 cm 

2.
a)
60 cm = 6 dm
430 cm = 43 dm
530 cm = 53 dm
1990 cm = 199 dm
b)
6 m = 60 dm
7 m = 70 dm
3 dm = 3 dm
9 m = 90 dm
8 dm = 8 dm
6 m = 60 dm
80 cm = 8 dm

3.
a)
60 dm = 6 m
500 dm = 50 m
280 dm = 28 m
960 dm = 96 m
b)
60 km = 6000 m
75 km = 75000 m
4 km = 4000 m
6 m = 6 m
9 km = 9000 m
25 m = 25 m

4.
a)
500mm = 5 dm
7500 dam = 75 km
b)
3600 dm = 36 dam
6 hm = 60000 cm
c)
6300 = 63 m
90 hm = 9000 m
