Compare the following by using `lt , gt` or `=`.
42, XLII

Answer

To compare the numbers 42 and XLII, we will first convert XLII from Roman numerals to its equivalent Arabic numeral (standard number).

### Step-by-Step Solution:

1. **Identify the Roman Numerals**:
- The Roman numeral given is XLII.

2. **Break Down the Roman Numerals**:
- In Roman numerals:
- X = 10
- L = 50
- I = 1
- XL means 50 - 10 = 40 (since X is before L, we subtract).
- II means 1 + 1 = 2 (since I is after I, we add).

3. **Calculate the Total Value of XLII**:
- Combine the values:
- XL = 40
- II = 2
- Therefore, XLII = 40 + 2 = 42.

4. **Compare the Two Values**:
- Now we have:
- The Arabic numeral 42
- The Roman numeral XLII, which we converted to 42.
- Since both values are equal, we can conclude that:
- 42 = XLII.

### Final Answer:
42 = XLII
