\(\frac{16ab^4}{-56a^3b^3}=-\frac{2b}{7a^2}\)
\(\frac{30a^2c^3}{48a^3c^2}=\frac{5c}{8a}\)
\(\frac{24x^5y^3}{56x^3y^2}=\frac{3x^2y}{7}\)
\(\frac{35a^2b^3}{10a^2bc^2}=\frac{7b^2}{2c^2}\)
\(\frac{12ab}{4a}=3b\)
\(\frac{14x^3y^2}{21xy^6}=\frac{2x^2}{3y^4}\)
\(\frac{12a^8c}{15a^2c^5}=\frac{4a^6}{5c^4}\)
\(\frac{16x^6y}{20x^2y^3}=\frac{4x^4}{5y^2}\)
\(\frac{15ac^8}{18a^5c^2}=\frac{5c^6}{6a^4}\)
\(\frac{4y^2}{2x}=\frac{2y^2}{x}\)
\(\frac{42x^3y^3}{28x^2y^4}=\frac{3x}{2y}\)
\(\frac{15a^2b^2}{18a^3b}=\frac{5b}{6a}\)
