26. Сократите дробь: а) $$rac{4a^2}{6ac}$$; б) $$rac{7x^2y}{21xy^2}$$; в) $$rac{56m^2n^5}{35mn^5}$$; г) $$rac{25p^4q}{100p^5q}$$

a) $$rac{4a^2}{6ac} = \frac{2a}{3c}$$ б) $$rac{7x^2y}{21xy^2} = \frac{x}{3y}$$ в) $$rac{56m^2n^5}{35mn^5} = \frac{8m}{5}$$ г) $$rac{25p^4q}{100p^5q} = \frac{1}{4p}$$
