Select the proper fractions from the fractions given below:
`5/(9), 11/(8), 23/(25), 19/(20), 18/(17), 3/(8), 12/(7), 5/(11), 15/(13), 17/(27)`

Answer

To solve the problem of selecting proper fractions from the given list, we need to first understand what a proper fraction is. A proper fraction is defined as a fraction where the numerator (the top number) is less than the denominator (the bottom number).

Let's analyze each fraction step by step:

1. **Fraction: 5/9**
- Numerator: 5
- Denominator: 9
- Since 5 < 9, this is a proper fraction.

2. **Fraction: 11/8**
- Numerator: 11
- Denominator: 8
- Since 11 > 8, this is not a proper fraction.

3. **Fraction: 23/25**
- Numerator: 23
- Denominator: 25
- Since 23 < 25, this is a proper fraction.

4. **Fraction: 19/20**
- Numerator: 19
- Denominator: 20
- Since 19 < 20, this is a proper fraction.

5. **Fraction: 18/17**
- Numerator: 18
- Denominator: 17
- Since 18 > 17, this is not a proper fraction.

6. **Fraction: 3/8**
- Numerator: 3
- Denominator: 8
- Since 3 < 8, this is a proper fraction.

7. **Fraction: 12/7**
- Numerator: 12
- Denominator: 7
- Since 12 > 7, this is not a proper fraction.

8. **Fraction: 5/11**
- Numerator: 5
- Denominator: 11
- Since 5 < 11, this is a proper fraction.

9. **Fraction: 15/13**
- Numerator: 15
- Denominator: 13
- Since 15 > 13, this is not a proper fraction.

10. **Fraction: 17/27**
- Numerator: 17
- Denominator: 27
- Since 17 < 27, this is a proper fraction.

Now, let's compile all the proper fractions we found:

- Proper fractions: 5/9, 23/25, 19/20, 3/8, 5/11, 17/27

### Final Answer:
The proper fractions from the given list are:
- 5/9
- 23/25
- 19/20
- 3/8
- 5/11
- 17/27
