Ta có:
\(A=0.3+0.5+0.7+0.9+1.1+1.3+1.5+1.7\)
\(A=0.2+0.4+0.6+0.8+1+1.2+1.4+0.1\cdot7+1.7=0.2+0.4+0.6+0.8+1+1.2+1.4+2.4\)
\(A=B+0.2\)
\(\Rightarrow A>B\)

\(x:\dfrac{5}{9}=\dfrac{3}{72}\)
\(x=\dfrac{3}{72}\cdot\dfrac{5}{9}\)
\(x=\dfrac{5}{216}\)

\(\dfrac{1}{10}\cdot\dfrac{2}{9}\cdot\dfrac{3}{8}\cdot\dfrac{4}{7}\cdot\dfrac{7}{4}\cdot\dfrac{8}{3}\cdot\dfrac{9}{2}=\dfrac{1\cdot2\cdot3\cdot4\cdot7\cdot8\cdot9}{10\cdot9\cdot8\cdot7\cdot4\cdot3\cdot2}=\dfrac{1}{10}\)
