\[ 2 - \frac{1}{5} = \frac{10}{5} - \frac{1}{5} = \frac{9}{5} \]
\[ \frac{1}{3} + \frac{4}{\frac{9}{5}} = \frac{1}{3} + 4 \times \frac{5}{9} \]
\[ 4 \times \frac{5}{9} = \frac{20}{9} \]
\[ \frac{1}{3} + \frac{20}{9} = \frac{3}{9} + \frac{20}{9} = \frac{23}{9} \]
\[ \frac{23}{9} = 2 \frac{5}{9} \]
Ответ: 2 5/9
