a) 20 cm = [tex]\frac{20}{100} m[/tex] = [tex]\frac{1}{5} m[/tex] 75 cm = [tex]\frac{75}{100} m[/tex] = [tex]\frac{3}{4} m[/tex]
b) 250 m = [tex]\frac{250}{1000} km[/tex] = [tex]\frac{1}{4} km[/tex] 800 m = [tex]\frac{800}{1000} km[/tex] = [tex]\frac{4}{5} km[/tex]
c) 35 dag = [tex]\frac{35}{1000} kg[/tex] = [tex]\frac{7}{200}[/tex] kg 600 g = [tex]\frac{600}{1000} kg[/tex] = [tex]\frac{3}{5} kg[/tex]
d) 650 kg = [tex]\frac{650}{1000}[/tex] t = [tex]\frac{13}{20}[/tex] t 40 kg = [tex]\frac{40}{1000} kg[/tex] = [tex]\frac{1}{25} kg[/tex]
