Convert mixed numbers to improper fractions with a common denominator, then add.<br><br>
&bull; \(2\frac{2}{5} = \frac{12}{5} = \frac{24}{10}\)<br>
&bull; \(1\frac{3}{10} = \frac{13}{10}\)<br>
&bull; \(\frac{24}{10} + \frac{13}{10} = \frac{37}{10}\)<br>
&bull; \(\frac{37}{10} = 3\frac{7}{10}\)<br><br>
Final Answer: \(3\frac{7}{10}\)
