Understanding Roman Numerals
Roman numerals are a numeral system originating from ancient Rome that uses combinations of letters from the Latin alphabet. Each letter represents a specific value, and they are combined to form numbers.
Key Roman Numerals
- I = 1
- V = 5
- X = 10
- L = 50
- C = 100
Breaking Down the Number 89
To convert the number 89 into Roman numerals, we can break it down as follows:
1. 80: This is represented as LXXX.
- L = 50
- XXX = 30 (which is 3 times 10)
- Therefore, LXXX = 50 + 30 = 80
2. 9: This is represented as IX.
- I (1) before X (10) indicates that we subtract 1 from 10, making it 9.
Combining the Parts
Now, when we combine these two parts:
- 80 (LXXX) + 9 (IX) = LXXXIX
Thus, the Roman numeral representation for the number 89 is LXXXIX.
Conclusion
Therefore, the correct answer is option 'A': LXXXIX. This accurately represents the number 89 in Roman numerals.
