write the following Roman numerals of . 329 ,98, 121 ,
The Correct Answer and Explanation is:
Here are the Roman numerals for the given numbers:
- 329 = CCCXXIX
- 98 = XCVIII
- 121 = CXXI
Explanation:
Roman numerals are a number system that originated in ancient Rome and are still used today in certain contexts. They use combinations of letters from the Latin alphabet, specifically seven symbols: I, V, X, L, C, D, and M. These symbols represent different values, and the system is based on adding and subtracting these symbols to form numbers.
- 329 (CCCXXIX):
- Start with “CCC” for 300, since C stands for 100, and three Cs add up to 300.
- “XX” represents 20, as X equals 10, and two X’s add up to 20.
- “IX” represents 9. In Roman numerals, when a smaller numeral appears before a larger one, it is subtracted. So, I (1) before X (10) means 10 – 1 = 9.
- Putting it together: CCC + XX + IX = 329.
- 98 (XCVIII):
- “XC” represents 90. The rule here is that the smaller numeral (I or V) before a larger one indicates subtraction, so X (10) before C (100) means 100 – 10 = 90.
- “VIII” represents 8. V (5) plus three I’s (1 + 1 + 1) equals 8.
- Thus, XCVIII represents 90 + 8 = 98.
- 121 (CXXI):
- “C” represents 100.
- “XX” represents 20, just like in the first number.
- “I” represents 1.
- Adding these together gives C + XX + I = 121.
Roman numerals follow specific rules for writing numbers. The numeral is typically written by starting with the highest value and working down to the lowest, using subtraction when a smaller numeral precedes a larger one. For instance, 4 is written as IV (5 – 1), and 9 as IX (10 – 1), which allows for a concise representation of numbers without unnecessary repetition.
