2; 4; 5; 27 со знаменателями 7 и 11

Answer 1

Пошаговое объяснение:

$3 \frac{1}{2} = \frac{7}{2} \\ 5 \frac{2}{3} = \frac{17}{3} \\ 4 \frac{3}{7} = \frac{31}{7} \\ 2 \frac{9}{10} = \frac{29}{10}$

$2 = \frac{2 \times 7}{7} = \frac{14}{7} \\ 4 = \frac{4 \times 7}{7} = \frac{28}{7} \\ 5 = \frac{5 \times 7}{7} = \frac{35}{7} \\ 27 = \frac{27 \times 7}{7} = \frac{189}{7} \\ \\ 2 = \frac{2 \times 11}{11} = \frac{22}{11} \\ 4 = \frac{4 \times 11}{11} = \frac{44}{11} \\ 5 = \frac{5 \times 11}{11} = \frac{55}{11} \\ 27 = \frac{27 \times 11}{11} = \frac{297}{11}$
