Сократите дробь (№ 285-287): 285 a) \frac{8}{12}, \frac{12}{16}, \frac{12}{18}, \frac{24}{40}, \frac{18}{27}, \frac{8}{36}

Сократим дроби:

• $$\frac{8}{12} = \frac{4 \cdot 2}{4 \cdot 3} = \frac{2}{3}$$
• $$\frac{12}{16} = \frac{4 \cdot 3}{4 \cdot 4} = \frac{3}{4}$$
• $$\frac{12}{18} = \frac{6 \cdot 2}{6 \cdot 3} = \frac{2}{3}$$
• $$\frac{24}{40} = \frac{8 \cdot 3}{8 \cdot 5} = \frac{3}{5}$$
• $$\frac{18}{27} = \frac{9 \cdot 2}{9 \cdot 3} = \frac{2}{3}$$
• $$\frac{8}{36} = \frac{4 \cdot 2}{4 \cdot 9} = \frac{2}{9}$$

Ответ: $$\frac{2}{3}$$, $$\frac{3}{4}$$, $$\frac{2}{3}$$, $$\frac{3}{5}$$, $$\frac{2}{3}$$, $$\frac{2}{9}$$
