а) \( \frac{2}{8} = \frac{2:2}{8:2} = \frac{1}{4} \)
б) \( \frac{15}{20} = \frac{15:5}{20:5} = \frac{3}{4} \)
в) \( \frac{18}{30} = \frac{18:6}{30:6} = \frac{3}{5} \)
г) \( \frac{24}{36} = \frac{24:12}{36:12} = \frac{2}{3} \)
д) \( \frac{9}{45} = \frac{9:9}{45:9} = \frac{1}{5} \)
е) \( \frac{64}{48} = \frac{64:16}{48:16} = \frac{4}{3} \)
