Solution

$\frac{2}{5} \times \frac{7}{3} + \frac{7}{6} \times \frac{25}{14} - \frac{18}{5} \times \frac{1}{6} = \frac{14}{15} + \frac{175}{84} - \frac{18}{30} = \frac{1}{3} (\frac{14}{5} + \frac{175}{28} - \frac{18}{10}) = \frac{1}{3} (\frac{392 + 875 - 252}{140}) = \frac{1}{3} \times \frac{1015}{140} = \frac{203}{84} = 2 \frac{35}{84}$
