2) \(3\frac{1}{5}-2\); \(3\frac{1}{5}+2\); \(3\frac{1}{5}\cdot2\); \(3\frac{1}{5}:2\).

\(3\frac{1}{5}=\frac{16}{5}\).

\(3\frac{1}{5}-2=\frac{16}{5}-\frac{10}{5}=\frac{6}{5}=1\frac{1}{5}\);

\(3\frac{1}{5}+2=\frac{16}{5}+\frac{10}{5}=\frac{26}{5}=5\frac{1}{5}\);

\(3\frac{1}{5}\cdot2=\frac{16}{5}\cdot2=\frac{32}{5}=6\frac{2}{5}\);

\(3\frac{1}{5}:2=\frac{16}{5}:2=\frac{16}{10}=\frac{8}{5}=1\frac{3}{5}\).

Ответ: \(1\frac{1}{5}; 5\frac{1}{5}; 6\frac{2}{5}; 1\frac{3}{5}\).
