Answer 2

Step-by-step explanation:

$= > \frac{ - 9}{16} + \frac{5}{12}$

• Make the denominators eqal

$= > \frac{ - 9 \: \times \: 12}{16 \: \times \: 12} \: + \: \frac{5 \: \times \: 16}{12 \: \times \: 16}$

$= > ( \frac{ - 108}{192} ) \: + \: ( \frac{80}{192}$ )

• Hence, denominators are same add the numerators directly

$= > \frac{( - 108) \: + \: 80}{192}$

$= = > \frac{ - 28}{192}$

OR

$= = > - 0.14584 \: \: \: approximately$
