1. Сократите дроби: 6/12; 8/12; 12/16; 14/21; 15/35; 850/1200; 216/360.

1. \(\frac{6}{12}=\frac{6:6}{12:6}=\frac{1}{2}\);
2. \(\frac{8}{12}=\frac{8:4}{12:4}=\frac{2}{3}\);
3. \(\frac{12}{16}=\frac{12:4}{16:4}=\frac{3}{4}\);
4. \(\frac{14}{21}=\frac{14:7}{21:7}=\frac{2}{3}\);
5. \(\frac{15}{35}=\frac{15:5}{35:5}=\frac{3}{7}\);
6. \(\frac{850}{1200}=\frac{850:50}{1200:50}=\frac{17}{24}\);
7. \(\frac{216}{360}=\frac{216:72}{360:72}=\frac{3}{5}\).

Ответ: \(\frac12;\ \frac23;\ \frac34;\ \frac23;\ \frac37;\ \frac{17}{24};\ \frac35\).
