Răspuns:

a)[tex]\frac{30}{12} =[/tex] ( simplificam cu 6 )

[tex]\frac{5}{2}[/tex] = 2,5

b) [tex]\frac{28}{42} =[/tex] (simplificam cu 14 )

[tex]\frac{2}{3}[/tex] = 0,(6)

c) [tex]\frac{32}{40}=[/tex] ( simplificam cu 8 )

[tex]\frac{4}{5}[/tex] = 0,8

d) [tex]\frac{45}{27} =[/tex] (simplificam cu 9 )

[tex]\frac{5}{3}[/tex] = 1,(6)

e) [tex]\frac{36}{48} =\\[/tex] ( simplificam cu 12 )

[tex]\frac{3}{4}[/tex] = 0,75

f) [tex]\frac{48}{54} =[/tex] ( simplificam cu 6 )
