Сокращаем дроби: 1. a) \(\frac{4}{6}\). Делим на 2: \(\frac{4 \div 2}{6 \div 2} = \frac{2}{3}\) б) \(\frac{15}{20}\). Делим на 5: \(\frac{15 \div 5}{20 \div 5} = \frac{3}{4}\) в) \(\frac{2}{4}\). Делим на 2: \(\frac{2 \div 2}{4 \div 2} = \frac{1}{2}\) г) \(\frac{6}{9}\). Делим на 3: \(\frac{6 \div 3}{9 \div 3} = \frac{2}{3}\) 2. a) \(\frac{30}{66}\). Делим на 6: \(\frac{30 \div 6}{66 \div 6} = \frac{5}{11}\) б) \(\frac{24}{40}\). Делим на 8: \(\frac{24 \div 8}{40 \div 8} = \frac{3}{5}\) в) \(\frac{27}{54}\). Делим на 27: \(\frac{27 \div 27}{54 \div 27} = \frac{1}{2}\) г) \(\frac{36}{84}\). Делим на 12: \(\frac{36 \div 12}{84 \div 12} = \frac{3}{7}\) 3. a) \(\frac{60}{100}\). Делим на 20: \(\frac{60 \div 20}{100 \div 20} = \frac{3}{5}\) б) \(\frac{75}{100}\). Делим на 25: \(\frac{75 \div 25}{100 \div 25} = \frac{3}{4}\) в) \(\frac{125}{1000}\). Делим на 125: \(\frac{125 \div 125}{1000 \div 125} = \frac{1}{8}\) г) \(\frac{25}{100}\). Делим на 25: \(\frac{25 \div 25}{100 \div 25} = \frac{1}{4}\)
