13. Сократите дробь: 1) 6m/(18n); 2) 14ab/(2at); 3) 16p³/(48p⁵); 4) 4mn²q/(28m²nq³); 5) 33a⁵b³/(44a⁴b⁷); 6) 34x⁸y⁶/(51x⁶y⁸).

1. \(\dfrac{6m}{18n}=\dfrac{m}{3n}\);
2. \(\dfrac{14ab}{2at}=\dfrac{7b}{t}\);
3. \(\dfrac{16p^3}{48p^5}=\dfrac{1}{3p^2}\);
4. \(\dfrac{4mn^2q}{28m^2nq^3}=\dfrac{n}{7mq^2}\);
5. \(\dfrac{33a^5b^3}{44a^4b^7}=\dfrac{3a}{4b^4}\);
6. \(\dfrac{34x^8y^6}{51x^6y^8}=\dfrac{2x^2}{3y^2}\).

Ответ: \(\dfrac{m}{3n};\ \dfrac{7b}{t};\ \dfrac{1}{3p^2};\ \dfrac{n}{7mq^2};\ \dfrac{3a}{4b^4};\ \dfrac{2x^2}{3y^2}\).
