Answer 1

$= \frac{ - 12}{10} + \frac{ - 90}{15} - \frac{3}{5} \\ = \frac{ - 36 + ( - 180)}{30} - \frac{3}{5} \\ = \frac{ - 216}{30} - \frac{3}{5} \\ = \frac{ - 216 - 18}{30} \\ = \frac{ - 224}{30}$

Answer 2

Step-by-step explanation:

Simplify

$( \frac{ - 3}{2} \times \frac{4}{5}) + ( \frac{9}{5} \times \frac{ - 10}{3} ) - ( \frac{1}{2} \times \frac{3}{4} ) \\ \\ \longrightarrow \: \frac{ - 6}{5} + (- 6) - \frac{3}{8} \\ \\ \longrightarrow \: \frac{ - 6}{5} - 6 - \frac{3}{8} \\ \\ \longrightarrow \: \frac{ - 48 - 240 - 15 }{40} \\ \\ \longrightarrow \: \frac{−303}{40}$
