Answer 1

Step-by-step explanation:

$\frac{2}{5} + ( - \frac{4}{7} + \frac{1}{4} )\\ = \frac{2}{5} + ( \frac{ - 4 \times 4 + 7 \times 1}{7 \times 4} ) \\ = \frac{2}{5} + \frac{ - 16 + 7}{28} \\ = \frac{2}{5} - \frac{9}{28 } \\ = \frac{2 \times 28 - 9 \times 5}{5 \times 28} \\ = \frac{56 - 45}{140} \\ = \frac{11}{140}$
