$1)\frac{18bc}{24c}=\frac{6c*3b}{6c*4}=\frac{3b}{4}\\\\2)\frac{25a^{2}y }{15by}=\frac{5y*5a^{2}}{5y*3b}=\frac{5a^{2}}{3b}\\\\3)\frac{24a^{3}}{6ac}=\frac{6a*4a^{2}}{6a*c}=\frac{4a^{2}}{c}\\\\4)\frac{27x^{2}y}{21xy^{3} }=\frac{3xy*9x}{3xy*7y^{2}}=\frac{9x}{7y^{2}}$

$5)\frac{-2a^{6}b^{3}}{a^{3}b^{5}} =\frac{a^{3}b^{3}*(-2a^{3})}{a^{3}b^{3}*b^{2}}=\frac{-2a^{3}}{b^{2}}\\\\6)\frac{x^{7}y^{4}}{x^{5}y^{8}}=\frac{x^{5}y^{4}*x^{2}}{x^{5}y^{4}*y^{4}}=\frac{x^{2}}{y^{4}}\\\\7)\frac{42m^{3}n^{5}}{35mn^{5}}=\frac{7mn^{5}*6m^{2}}{7mn^{5}*5}=\frac{6m^{2} }{5}\\\\8)\frac{75p^{4}q }{150p^{5}q}=\frac{75p^{4}q}{75p^{4}q*2p}=\frac{1}{2p}$
