2) Сократите дроби:

Решение:

Для сокращения дробей нужно найти наибольший общий делитель (НОД) числителя и знаменателя и разделить на него оба числа.

\( \frac{2}{8} = \frac{2 \div 2}{8 \div 2} = \frac{1}{4} \)

\( \frac{15}{18} = \frac{15 \div 3}{18 \div 3} = \frac{5}{6} \)

\( \frac{7}{28} = \frac{7 \div 7}{28 \div 7} = \frac{1}{4} \)

\( \frac{3}{9} = \frac{3 \div 3}{9 \div 3} = \frac{1}{3} \)

\( \frac{14}{34} = \frac{14 \div 2}{34 \div 2} = \frac{7}{17} \)

\( \frac{6}{12} = \frac{6 \div 6}{12 \div 6} = \frac{1}{2} \)

\( \frac{8}{44} = \frac{8 \div 4}{44 \div 4} = \frac{2}{11} \)

\( \frac{36}{63} = \frac{36 \div 9}{63 \div 9} = \frac{4}{7} \)

\( \frac{3}{54} = \frac{3 \div 3}{54 \div 3} = \frac{1}{18} \)

\( \frac{4}{64} = \frac{4 \div 4}{64 \div 4} = \frac{1}{16} \)

\( \frac{18}{48} = \frac{18 \div 6}{48 \div 6} = \frac{3}{8} \)

\( \frac{56}{72} = \frac{56 \div 8}{72 \div 8} = \frac{7}{9} \)

\( \frac{3}{87} = \frac{3 \div 3}{87 \div 3} = \frac{1}{29} \)

\( \frac{10}{45} = \frac{10 \div 5}{45 \div 5} = \frac{2}{9} \)

\( \frac{2}{38} = \frac{2 \div 2}{38 \div 2} = \frac{1}{19} \)

\( \frac{45}{63} = \frac{45 \div 9}{63 \div 9} = \frac{5}{7} \)

\( \frac{5}{35} = \frac{5 \div 5}{35 \div 5} = \frac{1}{7} \)

\( \frac{6}{66} = \frac{6 \div 6}{66 \div 6} = \frac{1}{11} \)

Ответ: \( \frac{1}{4}, \frac{5}{6}, \frac{1}{4}, \frac{1}{3}, \frac{7}{17}, \frac{1}{2}, \frac{2}{11}, \frac{4}{7}, \frac{1}{18}, \frac{1}{16}, \frac{3}{8}, \frac{7}{9}, \frac{1}{29}, \frac{2}{9}, \frac{1}{19}, \frac{5}{7}, \frac{1}{7}, \frac{1}{11} \)
