Let's break down and solve the questions from the image step by step:

### 1. **Calculate 10% of £6.40 (Answer in pence):**
   \[
   10\% \text{ of } 6.40 = \frac{10}{100} \times 6.40 = 0.64 \, \text{pounds}
   \]
   Since the answer is in pence, convert 0.64 pounds to pence:

   \]
   Convert 0.32 pounds to pence:
   \[
   0.32 \, \text{pounds} = 32 \, \text{pence}
   \]
   **Answer: 32 pence**

### 3. **Calculate 20% of £6.40 (Answer in pounds):**
