\(a.\frac{ababab}{cdcdcd}\)

\(=\frac{10000ab+100ab+ab}{10000cd+100cd+cd}\)

\(=\frac{ab\left(10000+100+1\right)}{cd\left(10000+100+1\right)}\)

\(=\frac{ab}{cd}\)

\(b.\frac{aaaa}{bbbb}\)

\(=\frac{1000a+100a+10a+a}{1000b+100b+10b+b}\)

\(=\frac{a\left(1000+100+10+1\right)}{b\left(1000+100+10+1\right)}\)

\(=\frac{a}{b}\)
