\(c,\overline{735a2b}⋮̸2;⋮5\Rightarrow b=5\\ \Rightarrow\overline{735a25}⋮9\\ \Rightarrow7+3+5+a+2+5⋮9\\ \Rightarrow22+a⋮9\\ \Rightarrow a=5\\ \Rightarrow\overline{735a2b}=735525\\ b,\overline{5a27b}⋮2;⋮5\Rightarrow b=0\\ \Rightarrow\overline{5a270}⋮9\\ \Rightarrow5+a+2+7+0⋮9\\ \Rightarrow14+a⋮9\\ \Rightarrow a=4\\ \Rightarrow\overline{5a27b}=54270\)

c) \(735525\)
d) \(54270\)

\(6\dfrac{1}{2}-2\dfrac{1}{3}:\dfrac{7}{15}\)

\(=\dfrac{13}{2}-\dfrac{7}{3}:\dfrac{7}{15}\)

\(=\dfrac{13}{2}-\dfrac{7}{3}\cdot\dfrac{15}{7}\)

\(=\dfrac{13}{2}-\dfrac{15}{3}\)

\(=\dfrac{13}{2}-5\)

\(=\dfrac{3}{2}\)
