Question

0,81 hm = Quantos dm
23 km = Quantos cm
0,003 6 = Quantos mm
11,4 mm = quantos cm
Quantos km = 0,53 m
78,4 dam = Quantos cm
Quantos m = 11,2 mm

Answer 1

1 hm = 1000 dm
0,81 hm * 1000  = 810 dm

1 km = 100000 cm
23 km * 100000 = 2300000 cm

1 cm = 10 mm
11,4mm : 10 = 1,14 cm

1 km = 1000 m
0,53 m :1000 = 0,00053 km

1 dam = 1000 cm
78,4 dam * 1000 = 78400 cm

1 m = 1000 mm
11,2 mm : 1000 = 0,0112 m
