.

• → - 3/4 × 2/4 + 5/2 - 2/5 × 1/7

.

• → - 3/8 + 5/2 - 2/35

.

• → -3/8 - 2/35 + 5/2

.

• → -121/280 + 5/2

.

• → 579/280

Answer 2

$\huge\boxed{\fcolorbox{red}{ink}{SOLUTION:}}$

Step-by-step explanation:

$→\frac{ - 3}{4} \times \frac{2}{4} + \frac{5}{2} - \frac{2}{5} \times \frac{1}{7} \\ \\ → \frac{ - 3}{8} + \frac{5}{2} - \frac{2}{75} \\ \\ → \frac{ - 3}{8} - \frac{2}{35} + \frac{5}{2} \\ \\ → \frac{121}{280} + \frac{5}{2} \\ \\ → \frac{579}{280}$
