Answer:
[tex] - \frac{11}{28} [/tex]
Step-by-step explanation:
[tex] \frac{2}{5} \bigg( - \frac{3}{7} \bigg) - \frac{1}{6} \times \frac{3}{2} + \frac{1}{14} \times \frac{2}{5} \\ \\
= - \frac{6}{35} - \frac{3}{12} + \frac{1}{35} \\ \\
= \frac{1 - 6}{35} - \frac{1}{4} \\ \\
= \frac{ - 5}{35} - \frac{1}{4} \\ \\
= \frac{ - 1}{7} - \frac{1}{4} \\ \\
= \frac{ - 1\times 4-1\times 7}{7\times 4} \\\\
= \frac{ - 4- 7}{28} \\\\
= -\frac{ 11}{28} \\\\
