To evaluate the expression:

$$
12.75 - \{4.38 - (2.4 \times 4.32 \div 3.6 - 0.85)\}
$$

follow these step-by-step calculations:

1. **Calculate the multiplication inside the innermost parentheses:**

$$
   2.4 \times 4.32 = 10.368
   $$

2. **Divide the result by 3.6:**

$$
   10.368 \div 3.6 = 2.88
   $$

3. **Subtract 0.85 from the division result:**

$$
   2.88 - 0.85 = 2.03
   $$

4. **Subtract this result from 4.38:**

$$
   4.38 - 2.03 = 2.35
   $$

5. **Finally, subtract this from 12.75:**

$$
   12.75 - 2.35 = 10.40
   $$

**Final Answer:**

$$
10.40
$$
The final answer is 10.40.
