Question

-12/5+31/10+11/-15+-7/-18

Answer 1

Hey friend,
Here is the answer you were looking for:
$- \frac{12}{5} + \frac{31}{10} + \frac{11}{ - 15} + ( \frac{ - 7}{ - 18} ) \\ \\ = - \frac{12}{5} + \frac{31}{10} - \frac{11}{15} + \frac{7}{18}$
Taking LCM we get 90

$= \frac{ - 12 \times 18 + 31 \times 9 - 11 \times 6 + 7 \times 5}{90} \\ \\ = \frac{ - 216 + 279 - 66 + 35}{90} \\ \\ = \frac{314 - 282}{90} \\ \\ = \frac{32}{90}$

Hope this helps!!
