Explanation:
Roman numerals are a system of numerical notation used in ancient Rome, consisting of combinations of the letters I, V, X, L, C, D, and M. The basic Roman numeral symbols and their values are:
- I = 1
- V = 5
- X = 10
- L = 50
- C = 100
- D = 500
- M = 1000
Roman numerals are generally written from largest to smallest, with the exception that when a smaller numeral appears before a larger one, it is subtracted. For example, IV means 4 (5 minus 1), and IX means 9 (10 minus 1).
To represent the number 24 in Roman numerals, it is broken down into the sum of 20 and 4.
- The number 20 is represented as XX (two X’s, each representing 10).
- The number 4 is represented as IV (5 minus 1).
Thus, the number 24 is written as XXIV in Roman numerals.
Looking at the choices:
- A. XIV represents 14 (10 + 4).
- B. XXIV represents 24 (10 + 10 + 4), which is the correct answer.
- C. XXV represents 25 (10 + 10 + 5).
- D. XXIX represents 29 (10 + 10 + 9).
Therefore, the correct answer is B. XXIV because it accurately represents 24 in Roman numeral form.
