Write the given number in roman system.
545

Answer

To convert the number 545 into the Roman numeral system, we can follow these steps:

### Step-by-Step Solution:

1. **Identify the Roman Numerals**:
- The Roman numeral system uses specific letters to represent values:
- D = 500
- L = 50
- X = 10
- V = 5

2. **Break Down the Number**:
- We need to express 545 in terms of these Roman numerals.
- First, we can split 545 into two parts: 500 and 45.
- So, 545 = 500 + 45.

3. **Convert 500 to Roman Numerals**:
- The number 500 is represented by the letter D in Roman numerals.
- Therefore, we write: 500 = D.

4. **Convert 45 to Roman Numerals**:
- Next, we need to convert 45 into Roman numerals.
- We can break down 45 into 50 - 5, which can be represented as:
- 50 is represented by L.
- 5 is represented by V.
- To express 45, we can write it as 50 (L) minus 10 (X) plus 5 (V).
- Thus, 45 = L - X + V.

5. **Combine the Roman Numerals**:
- Now we combine the Roman numeral representations:
- For 500, we have D.
- For 45, we have L - X + V.
- Therefore, we can write: 545 = D + (L - X + V).

6. **Final Representation**:
- In Roman numerals, we write it as:
- D (for 500) + XL (for 40) + V (for 5).
- Thus, 545 in Roman numerals is **DLXLV**.

### Final Answer:
545 in Roman numerals is **DLXLV**.
