Answer 5

\(A=10\dfrac{1}{7}+3\dfrac{4}{5}-\left(2\dfrac{4}{5}+5\dfrac{1}{7}\right)\)

\(\Rightarrow A=\dfrac{71}{7}+\dfrac{19}{5}-\left(\dfrac{14}{5}+\dfrac{36}{5}\right)\)

\(\Rightarrow A=\dfrac{71}{7}+\dfrac{19}{5}-10\)

\(\Rightarrow A=\dfrac{355}{35}+\dfrac{133}{35}-\dfrac{350}{35}\)

\(\Rightarrow A=\dfrac{138}{35}\)
