Let's go through the questions from the image you uploaded:

### Question 1:
(a) **Calculate** \( \frac{12.6^2 - 4}{\sqrt{25} - 3} \)

This is a calculation problem where we are asked to evaluate the given expression step by step:
\[
\frac{12.6^2 - 4}{\sqrt{25} - 3}
\]

Steps:
1. \( 12.6^2 = 158.76 \)
2. \( \sqrt{25} = 5 \)
3. Subtract the values:
   - Numerator: \( 158.76 - 4 = 154.76 \)
   - Denominator: \( 5 - 3 = 2 \)
4. Finally, \( \frac{154.76}{2} = 77.38 \)

The first five digits are **77.380**.

(b) **Write the answer to part (a) correct to two decimal places:**
Answer is **77.38**.

### Question 2:
Express 32% as:
(a) **Fraction:**
- 32% means \( \frac{32}{100} \), which simplifies to \( \frac{8}{25} \).

(b) **Decimal:**
- 32% is the same as 0.32.

### Question 3:
(a) **Round off 35.492 to the nearest whole number:**
- The nearest whole number is **35**.
