2. **Examine Each Fraction**:
- **Fraction 1: 7/10**
- Here, the numerator is 7 and the denominator is 10.
- Since 7 < 10, this is a proper fraction.

- **Fraction 2: 7/9**
- Here, the numerator is 7 and the denominator is 9.
- Since 7 < 9, this is also a proper fraction.

- **Fraction 3: 9/7**
- Here, the numerator is 9 and the denominator is 7.
- Since 9 > 7, this is an improper fraction.

- **Fraction 4: 7/7**
- Here, the numerator is 7 and the denominator is 7.
- Since 7 = 7, this is equal to 1, which is not considered an improper fraction.
