Explanation:

Let’s break it down step by step:

- The expression given is: .1.5 - 0.5 {(9 + 2 - 5}

It looks like it was meant to be: 1.5 - 0.5 × (9 + 2 - 5)

(Usually, using curly brackets means multiplying whatever’s outside by whatever’s inside.)

- First, handle inside the brackets:

9 + 2 - 5 = 6

- Next, multiply 0.5 × 6 = 3

- Now, subtract:

1.5 - 3 = -1.5

Here’s where we land:

- Option 1: 7 – Doesn’t match

- Option 2: 11 – Doesn’t match

- Option 3: 9 – Doesn’t match

- Option 4: 5 – Doesn’t match

The correct answer should actually be -1.5, which isn’t on the list.
