### Step-by-Step Solution:

1. **Convert 0.8 to a Percentage:**
- Multiply 0.8 by 100.

- Therefore, \( 0.8 = 80\% \).

2. **Convert 0.36 to a Percentage:**
- Multiply 0.36 by 100.
- Calculation: \( 0.36 \times 100 = 36 \)
- Therefore, \( 0.36 = 36\% \).

3. **Convert 0.04 to a Percentage:**
- Multiply 0.04 by 100.
- Calculation: \( 0.04 \times 100 = 4 \)
- Therefore, \( 0.04 = 4\% \).

4. **Convert 0.008 to a Percentage:**
- Multiply 0.008 by 100.
- Calculation: \( 0.008 \times 100 = 0.8 \)
- Therefore, \( 0.008 = 0.8\% \).

### Final Answers:
1. \( 0.8 = 80\% \)
2. \( 0.36 = 36\% \)
3. \( 0.04 = 4\% \)
