[latex] \frac{24a^6*b^4}{16a^3b^7} = \frac{3a^3}{2b^3} \\ \\ \frac{15x-10xy}{5xy}= \frac{5x(3-2y)}{5xy}= \frac{3-2y}{y} \\ \\ \frac{m^2-4}{2m-4}= \frac{(m-2)(m+2)}{2(m-2)}= \frac{m+2}{2} [/latex]

1) [latex] \frac{24a^6b^4}{16a^3b^7} [/latex] = [latex] \frac{ab(24a^5b^3)}{ab(16a^2b^6)} [/latex] = [latex] \frac{24a^5b^3}{16a^2b^6} [/latex] = [latex] \frac{3a^3}{2b^3} [/latex] 2)  [latex] \frac{15x-10xy}{5xy} [/latex] = [latex] \frac{5x(3-2y)}{5xy} [/latex] = [latex] \frac{3-2y}{y} [/latex] 3) [latex] \frac{m^2-4}{2m-4} [/latex] = [latex] \frac{m^2-2^2}{2(m-2)} [/latex] = [latex] \frac{(m-2)(m+2)}{2(m-2)} [/latex] = [latex] \frac{m+2}{2} [/latex]
