Answer:

-23/7

Step-by-step explanation:

${ \huge(}\frac{2}{5} + \frac{3}{4} { \huge)} \div { \huge( }\frac{2}{5} - \frac{3}{4} { \huge) }\\ ={ \huge ( }\frac{8 + 15}{20}{ \huge ) }\div { \huge( }\frac{8 - 15}{20} { \huge) }\\ = \frac{23}{20} \div \frac{ - 7}{20} \\ = \frac{23}{ \cancel{20}} \times \frac{ \cancel{20}}{ - 7} \\ = \frac{ - 23}{7}$
