4 2/5+1 2/3×1/2-3/5:2/5=

$4 \frac{2}{5} + 1 \frac{2}{3} \times \frac{1}{2} - \frac{3}{5} \div \frac{2}{5} \\ \\ = \frac{22}{5} + (\frac{5}{3} \times \frac{1}{2} ) - (\frac{3}{5} \times \frac{5}{2} ) \\ \\ = \frac{22}{5} + \frac{5}{6} - \frac{3}{2} \\ \\ = \frac{132 + 25 - 45}{30} = \frac{112}{30} = 3 \frac{22}{30} = 3 \frac{11}{15}$
