Let's solve the two questions shown in the image:

### Problem 35:
**1 Km - 9 Hm - 40 dm = ____ m**

We need to convert each unit to meters.

- \( 1 \text{ Km} = 1000 \text{ m} \)
- \( 9 \text{ Hm} = 9 \times 100 = 900 \text{ m} \)
- \( 40 \text{ dm} = 40 \times 0.1 = 4 \text{ m} \)

Now perform the subtraction:
\[
1000 - 900 - 4 = 96 \text{ m}
\]

So, the answer is **96 m**.

### Problem 36:
\[
(5.5 \times 10) \div ((-88) + (-2)) = ?
\]

1. Calculate \( 5.5 \times 10 = 55 \)
2. Calculate \( (-88) + (-2) = -90 \)
3. Now divide:
\[
55 \div (-90) = -\frac{55}{90} = -\frac{11}{18}
\]

So, the final answer is **-\(\frac{11}{18}\)**.
