Răspuns :

[tex] \frac{80}{120} = \frac{16}{24} \\ \\ \frac{150}{50} = \frac{30}{10} = \frac{6}{2} =3 \\ \\ \frac{190}{125} = \frac{38}{25} \\ \\ \frac{25}{35} = \frac{5}{7 } \\ \\ \frac{170}{360} = \frac{34}{72} \\ \\ \frac{2^2*5^3}{2^3*5^2} = \frac{4*125}{8*25} = \frac{500}{200} = \frac{100}{40}= \frac{20}{8} \\ \\ \frac{2*3^2*5^3}{7*5*11} = \frac{2*9*125}{385} = \frac{2250}{385} = \frac{450}{77} [/tex]
