| Fraction Form | Decimal Form | Percent Form      |
|---------------|--------------|-------------------|
| 1. | \(\frac{1}{40}\)        | 0.025        | 2.5%             |
| 2. |                | 0.62         | 62% (?)            |

**Explanation of Example Conversions:**
- For row 1:
  - **Fraction Form:** \(\frac{1}{40}\)
  - **Decimal Form:** \(\frac{1}{40} = 0.025\)
  - **Percent Form:** \(0.025 \times 100 = 2.5\%\)

- For row 2:
  - **Decimal Form:** 0.62 
  - **Percent Form:** \(0.62 \times 100 = 62\%\)

- For row 3:
