a=\(\frac{6.7.8.9}{2.9.2.8.2.7.2.6}=\frac{1}{2.2.2.2}=\frac{1}{16}\)
b=\(\frac{4.3.5.9.2.12}{3.12.2.4.5}=\frac{9}{1}=9\)
a) \(\frac{6.7.8.9}{18.16.14.12}\)
\(=\frac{6.7.8.9}{9.2.8.2.7.2.6.2}=\frac{1}{2.2.2}=\frac{1}{8}\)
b) \(\frac{4.15.9.24}{3.12.8.5}\)
\(=\frac{4.5.3.9.2.12}{3.12.2.4.5}=\frac{9}{1}=9\)
