Every fraction is a rational number.

Answer

**Step-by-Step Solution:**

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

2. **Defining Fractions**:
- A fraction is a mathematical expression that represents the division of one integer by another. It is written in the form \( \frac{a}{b} \), where \( a \) (the numerator) and \( b \) (the denominator) are integers, and \( b \neq 0 \).

3. **Connecting Fractions to Rational Numbers**:
- Since a fraction can be expressed as \( \frac{a}{b} \) and both \( a \) and \( b \) are integers with \( b \neq 0 \), it fits the definition of a rational number.

4. **Conclusion**:
- Therefore, every fraction is indeed a rational number because it can be expressed in the form \( \frac{P}{Q} \) where \( P \) and \( Q \) are integers and \( Q \neq 0 \).

**Final Answer**: True, every fraction is a rational number.
