Answer 1

a: \(\dfrac{6\cdot8\cdot12\cdot16}{4\cdot12\cdot6\cdot8}=\dfrac{8\cdot12}{12\cdot8}\cdot\dfrac{6\cdot16}{4\cdot6}=\dfrac{16}{4}=4\)

b: \(=\dfrac{5\cdot7\cdot9\cdot11}{27\cdot5\cdot7\cdot11}=\dfrac{9}{27}=\dfrac{1}{3}\)

Answer 2

\(\dfrac{6\times8\times12\times16}{4\times12\times6\times8}=\dfrac{16}{4}=4\\ \dfrac{5\times7\times9\times11}{27\times5\times7\times11}=\dfrac{9}{27}=\dfrac{1}{3}\)
