[tex]2 \frac{2}{5} + 1 \frac{1}{3} \div \frac{2}{5} \times \frac{1}{5} + 1 \frac{2}{5} \\ \\ = \frac{12}{5} + (\frac{4}{3} \times \frac{5}{2} \times \frac{1}{5} ) + \frac{7}{5} \\ \\ = \frac{12}{5} + \frac{20}{30} + \frac{7}{5} \\ \\ = \frac{72 + 20 + 42}{30} \\ \\ = \frac{134}{30} \\ \\ = 4 \frac{7}{15} [/tex]
