1. Сократите:$$\frac{8}{14}$$, $$\frac{7}{63}$$, $$\frac{30}{84}$$, $$\frac{34 \cdot 12}{3 \cdot 17}$$

1. * $$\frac{8}{14} = \frac{4}{7}$$ * $$\frac{7}{63} = \frac{1}{9}$$ * $$\frac{30}{84} = \frac{5}{14}$$ * $$\frac{34 \cdot 12}{3 \cdot 17} = \frac{2 \cdot 12}{3} = \frac{24}{3} = 8$$ Ответ:$$\frac{4}{7}$$, $$\frac{1}{9}$$, $$\frac{5}{14}$$, $$8$$
