Наименьший общий знаменатель выбираем как НОК знаменателей.

  1. НОК(8, 6) = 24: \(\frac{3}{8}=\frac{9}{24}\), \(\frac{1}{6}=\frac{4}{24}\).
  2. НОК(9, 6) = 18: \(\frac{4}{9}=\frac{8}{18}\), \(\frac{5}{6}=\frac{15}{18}\).
  3. НОК(9, 18) = 18: \(\frac{2}{9}=\frac{4}{18}\), \(\frac{5}{18}=\frac{5}{18}\).
  4. НОК(5, 8) = 40: \(\frac{4}{5}=\frac{32}{40}\), \(\frac{3}{8}=\frac{15}{40}\).
  5. НОК(12, 18) = 36: \(\frac{5}{12}=\frac{15}{36}\), \(\frac{7}{18}=\frac{14}{36}\).
  6. НОК(10, 8, 4) = 40: \(\frac{7}{10}=\frac{28}{40}\), \(\frac{5}{8}=\frac{25}{40}\), \(\frac{1}{4}=\frac{10}{40}\).
