Answer 1

➤ Answer :-

$\longrightarrow \sf \: \bigg( \frac{ - 3}{4} \times \frac{2}{5} \bigg) + \bigg( - \frac{3}{4} \times \frac{7}{5} \bigg)$

$\longrightarrow \sf \bigg( \frac{ (- 3) \times 2}{4 \times 5} \bigg) + \bigg ( - \frac{3 \times 7}{4 \times 5} \bigg)$

$\longrightarrow \sf \: \bigg( \frac{ - 6}{20} \bigg) + \bigg( - \frac{21}{20} \bigg)$

$\longrightarrow \sf \: \frac{ - 6}{20} - \frac{21}{20}$

$\longrightarrow \sf \: \frac{( - 6) - 21}{20}$

$\longrightarrow \sf \: \frac{ - 27}{20}$

$\Huge\therefore$The answer is $\sf\frac{-27}{20}$
