Answer 1

Answer:

-12

Step-by-step explanation:

$</p><p>9 \times \frac{1}{2} - (7 \ \frac{1}{2} + (4 - (5 - 4 - 2) \\ = </p><p>9 \times \frac{1}{2} - (7 \ \frac{1}{2} + (4 - ( - 1)) \\ = 9 \times \frac{1}{2} - (7 \ \frac{1}{2} + (4 + 5) )\\ = 9 \times \frac{1}{2} - ( \frac{15}{2} + 9) \\ = \frac{9}{2} - ( \frac{15 + 18}{2} ) \\ = \frac{9}{2} - \frac{33}{2} \\ = \frac{9 - 33}{2} = \frac{ - 24}{2} \\ = - 12$
