$using \: bodmas$

$\frac{3}{5 } \times \frac{ - 4}{7} - \frac{1}{6} \times \frac{3}{2} \ + \frac{1}{14} \times \frac{3}{5}$

$= - \frac{12}{35} - \frac{3}{12} + \frac{3}{70}$

$= - \frac{24}{70} + \frac{3}{70} - \frac{1}{4}$

$= - \frac{21}{70} - \frac{1}{4} \\ = \frac{ - 3}{10} - \frac{1}{4} = \frac{ - 12 - 10}{40} = \frac{ - 22}{40}$

$= - \frac{11}{20}$
