The task in the image involves converting Roman numerals to their corresponding Arabic numeral equivalents. Here's how to solve it step by step:
Known Information:
-
Column A contains Roman numerals.
-
Column B contains the Arabic numeral equivalents of the Roman numerals.
Given Examples:
1.
LV (Roman numeral) =
50 (Arabic numeral)
2.
XIX (Roman numeral) =
19 (Arabic numeral)
Solution Approach:
To solve this, we need to understand the rules of Roman numerals and convert them to Arabic numerals. Here are the key rules for Roman numerals:
1.
Symbols and Values:
- I = 1
- V = 5
- X = 10
- L = 50
- C = 100
- D = 500
- M = 1000
2.
Addition Rule: If a smaller numeral appears after a larger numeral, you add the values.
- Example: VI = 5 + 1 = 6
3.
Subtraction Rule: If a smaller numeral appears before a larger numeral, you subtract the smaller value from the larger value.
- Example: IV = 5 - 1 = 4
- Example: IX = 10 - 1 = 9
Step-by-Step Conversion:
Let’s assume additional Roman numerals are provided in Column A. For demonstration purposes, let’s fill in some common examples:
#### Example 1:
XXV
- Breakdown: XX = 10 + 10 = 20, V = 5
- Total: 20 + 5 = 25
- Answer:
25
#### Example 2:
XL
- Breakdown: X = 10, L = 50
- Since X is before L, subtract: 50 - 10 = 40
- Answer:
40
#### Example 3:
XC
- Breakdown: X = 10, C = 100
- Since X is before C, subtract: 100 - 10 = 90
- Answer:
90
#### Example 4:
MCM
- Breakdown: M = 1000, CM = 900 (C before M means 1000 - 100 = 900)
- Total: 1000 + 900 = 1900
- Answer:
1900
General Steps:
1. Identify each Roman numeral in Column A.
2. Use the addition and subtraction rules to convert it to an Arabic numeral.
3. Write the Arabic numeral in the corresponding box in Column B.
Final Answer:
If more Roman numerals were provided in the image, you would follow the same process to convert each one. Since no additional Roman numerals are shown in the image, the solution is based on the given examples and the explanation above.
If you have specific Roman numerals to convert, feel free to provide them, and I can help with the conversions!
Final Answer (based on the given examples):
\[
\boxed{50, 19}
\]
