26. Сократите дробь: а) \(\frac{10a^2}{15a^2}\); б) \(\frac{6ab^2}{9bc^2}\); в) \(\frac{20y^3}{-40y^2}\); г) \(\frac{-6p^2q}{-2q^3}\); д) \(\frac{24a^2c^2}{36ac}\); е) \(\frac{60p^2}{40p^2}\).

1. а) \(\frac{10a^2}{15a^2}=\frac{2}{3}\).
2. б) \(\frac{6ab^2}{9bc^2}=\frac{2ab}{3c^2}\).
3. в) \(\frac{20y^3}{-40y^2}=-\frac{y}{2}\).
4. г) \(\frac{-6p^2q}{-2q^3}=\frac{3p^2}{q^2}\).
5. д) \(\frac{24a^2c^2}{36ac}=\frac{2ac}{3}\).
6. е) \(\frac{60p^2}{40p^2}=\frac{3}{2}\).

Ответ: а) \(\frac23\); б) \(\frac{2ab}{3c^2}\); в) \(-\frac y2\); г) \(\frac{3p^2}{q^2}\); д) \(\frac{2ac}{3}\); е) \(\frac32\).
