Which of the following numbers are rational? Also, identify the irrational numbers.
0

Answer

To determine whether the number 0 is rational or irrational, we can follow these steps:

### Step-by-Step Solution:

1. **Understanding Rational Numbers**:
A rational number is defined as any number that can be expressed in the form \( \frac{p}{q} \), where \( p \) and \( q \) are integers, and \( q \neq 0 \).

2. **Expressing Zero in Fraction Form**:
We can express the number 0 as \( \frac{0}{1} \). Here, \( p = 0 \) and \( q = 1 \).

3. **Checking the Conditions**:
- Both \( p \) and \( q \) are integers (0 and 1, respectively).
- \( q \) is not zero (1 is not zero).
- Therefore, 0 can be expressed in the form \( \frac{p}{q} \).

4. **Conclusion**:
Since 0 can be expressed as \( \frac{0}{1} \), it meets the criteria for being a rational number. Thus, we conclude that **0 is a rational number**.

### Summary:
- **Rational Numbers**: 0
- **Irrational Numbers**: None in this case.
