1). Сократите дроби: 27/30, 50/75, 112/80

Решение:

• \[ \frac{27}{30} = \frac{27 \div 3}{30 \div 3} = \frac{9}{10} \]
• \[ \frac{50}{75} = \frac{50 \div 25}{75 \div 25} = \frac{2}{3} \]
• \[ \frac{112}{80} = \frac{112 \div 16}{80 \div 16} = \frac{7}{5} \]

Ответ: \[ \frac{9}{10}, \frac{2}{3}, \frac{7}{5} \]
