Ответ:

а) НОЗ(5, 3) = 15:

\(\frac{4}{5}=\frac{12}{15}\), \(\frac{1}{3}=\frac{5}{15}\).

б) НОЗ(7, 14) = 14:

\(\frac{4}{7}=\frac{8}{14}\), \(\frac{11}{14}=\frac{11}{14}\).

в) НОЗ(36, 24) = 72:

\(\frac{7}{36}=\frac{14}{72}\), \(\frac{7}{24}=\frac{21}{72}\).

г) НОЗ(375, 300) = 1500:

\(\frac{111}{375}=\frac{444}{1500}\), \(\frac{103}{300}=\frac{515}{1500}\).

Ответ: а) \(\frac{12}{15}\) и \(\frac{5}{15}\); б) \(\frac{8}{14}\) и \(\frac{11}{14}\); в) \(\frac{14}{72}\) и \(\frac{21}{72}\); г) \(\frac{444}{1500}\) и \(\frac{515}{1500}\).
