1. Сократите дроби: $$\frac{6}{12}, \frac{8}{12}, \frac{12}{16}, \frac{14}{21}, \frac{15}{35}, \frac{850}{1200}, \frac{216}{360}$$

Разберем каждую дробь по отдельности и сократим их: * $$\frac{6}{12} = \frac{6 \div 6}{12 \div 6} = \frac{1}{2}$$ * $$\frac{8}{12} = \frac{8 \div 4}{12 \div 4} = \frac{2}{3}$$ * $$\frac{12}{16} = \frac{12 \div 4}{16 \div 4} = \frac{3}{4}$$ * $$\frac{14}{21} = \frac{14 \div 7}{21 \div 7} = \frac{2}{3}$$ * $$\frac{15}{35} = \frac{15 \div 5}{35 \div 5} = \frac{3}{7}$$ * $$\frac{850}{1200} = \frac{850 \div 50}{1200 \div 50} = \frac{17}{24}$$ * $$\frac{216}{360} = \frac{216 \div 72}{360 \div 72} = \frac{3}{5}$$ Ответ: $$\frac{1}{2}, \frac{2}{3}, \frac{3}{4}, \frac{2}{3}, \frac{3}{7}, \frac{17}{24}, \frac{3}{5}$$
