Запишите частное в виде дроби и сократите дробь: 1) -6ax : (-18ax); 2) 6ab² : (9bc²); 3)...

Решите задачу:

$\displaystyle 1)..-6ax:(-18ax)= \frac{-6ax}{-18ax}= \frac{6}{18}= \frac{1}{3} \\ \\ 2)..6ab^{2}:(9bc^{2})= \frac{6ab^{2}}{9bc^{2}}= \frac{2ab}{3c^{2}} \\ \\ 3)..3day:(6ay^{3})= \frac{3day}{6ay^{3}}= \frac{d}{2y^{2}} \\ \\ 4)..-32b^{5}c:(12b^{4}c^{2})=- \frac{32b^{5}c}{12b^{4}c^{2}}=- \frac{8b}{3c} \\ \\ 5)..(6xy-18x^{2}):(y-3x)^{3}= \frac{6x(y-3x)}{(y-3x)^{3}}= \frac{6x}{(y-3x)^{2}}$
