- L = 50
- C = 100

2. **Break Down the Number 80**:
- The number 80 can be broken down into its components. We can express 80 as:
- 80 = 50 + 30

3. **Convert Each Component to Roman Numerals**:
- The Roman numeral for 50 is **L**.
- The number 30 can be expressed as:
- 30 = 10 + 10 + 10, which is represented as **XXX** in Roman numerals.

4. **Combine the Roman Numerals**:
