Answer 1

-1.4.......i hope it's correct

Answer 2

$\frac{ - 3}{15} + \frac{ - 2}{4} - \frac{ - 7}{10} \\ \\ = \frac{ - 3}{15} - \frac{2}{4} + \frac{7}{10}$

$= \frac{( - 3 \times 4) - (2 \times 15) + (7 \times 6)}{60} \\ \\ = \frac{ - 12 - 30 + 42}{60}$

$= \frac{ - 42 + 42}{60} \\ \\ = \frac{0}{60} \\ \\ = 0$
