57. Сократите дроби на наибольший общий делитель числителя и знаменателя: $$\frac{8}{16}$$, $$\frac{10}{25}$$, $$\frac{18}{27}$$, $$\frac{30}{45}$$, $$\frac{200}{350}$$, $$\frac{30}{25}$$, $$\frac{16}{24}$$, $$\frac{16}{80}$$, $$\frac{16}{96}$$

Сокращение дробей на наибольший общий делитель числителя и знаменателя:

1. $$\frac{8}{16}$$ = $$\frac{8:8}{16:8}$$ = $$\frac{1}{2}$$
2. $$\frac{10}{25}$$ = $$\frac{10:5}{25:5}$$ = $$\frac{2}{5}$$
3. $$\frac{18}{27}$$ = $$\frac{18:9}{27:9}$$ = $$\frac{2}{3}$$
4. $$\frac{30}{45}$$ = $$\frac{30:15}{45:15}$$ = $$\frac{2}{3}$$
5. $$\frac{200}{350}$$ = $$\frac{200:50}{350:50}$$ = $$\frac{4}{7}$$
6. $$\frac{30}{25}$$ = $$\frac{30:5}{25:5}$$ = $$\frac{6}{5}$$
7. $$\frac{16}{24}$$ = $$\frac{16:8}{24:8}$$ = $$\frac{2}{3}$$
8. $$\frac{16}{80}$$ = $$\frac{16:16}{80:16}$$ = $$\frac{1}{5}$$
9. $$\frac{16}{96}$$ = $$\frac{16:16}{96:16}$$ = $$\frac{1}{6}$$

Ответ: $$\frac{1}{2}$$, $$\frac{2}{5}$$, $$\frac{2}{3}$$, $$\frac{2}{3}$$, $$\frac{4}{7}$$, $$\frac{6}{5}$$, $$\frac{2}{3}$$, $$\frac{1}{5}$$, $$\frac{1}{6}$$
