Write the following in Roman numerals.
497

Answer

To convert the number 497 into Roman numerals, we can break it down into its constituent parts: hundreds, tens, and units.

### Step-by-Step Solution:

1. **Break Down the Number**:
- 497 can be broken down into 400 + 90 + 7.

2. **Convert Each Part to Roman Numerals**:
- **400**: In Roman numerals, 400 is represented as **CD** (C is 100, and D is 500; thus, CD means 500 - 100 = 400).
- **90**: In Roman numerals, 90 is represented as **XC** (X is 10, and C is 100; thus, XC means 100 - 10 = 90).
- **7**: In Roman numerals, 7 is represented as **VII** (V is 5 and II is 2, so V + II = 7).

3. **Combine the Roman Numerals**:
- Now, we combine the Roman numerals we found:
- 400 (CD) + 90 (XC) + 7 (VII) = CD + XC + VII.

4. **Final Answer**:
- Therefore, 497 in Roman numerals is **CDXCVII**.
