Roman Numerals Quiz

Explanation
XCI is a Roman numeral representation for the number 91. In Roman numerals, X represents 10, C represents 100, and I represents 1. When X (10) is subtracted from C (100), it leaves 90. Adding I (1) to 90 gives the value 91. Therefore, XCI is equal to 91.

Explanation
XLII is a Roman numeral representation for the number 42. In Roman numerals, X represents 10, L represents 50, and I represents 1. By combining these symbols, we get XLII, which represents 10 (X) + 50 (L) - 1 (I) - 1 (I) = 42. Therefore, the correct answer is 42.

Explanation
LXXI is a Roman numeral representation of the number 71. In Roman numerals, L represents 50, X represents 10, and I represents 1. When these symbols are combined, LXXI is formed, which represents 50 + 10 + 10 + 1 = 71. Therefore, the correct answer is 71.

Explanation
XLVII is a Roman numeral representation for the number 47. In Roman numerals, X represents 10, L represents 50, and V represents 5. When a smaller numeral is placed before a larger numeral, it is subtracted from the larger numeral. In this case, the X is placed before the L, which means we subtract 10 from 50, resulting in 40. The V and I after the X are added to the 40, giving us a total of 47. Therefore, the correct answer is 47.

Explanation
XCIII is a Roman numeral representation of the number 93. In Roman numerals, X represents 10 and C represents 100, while I represents 1. When a smaller numeral appears before a larger one, it is subtracted from the larger numeral. In this case, the smaller numeral I appears before X, so it is subtracted from X, resulting in 10 - 1 = 9. The larger numeral C appears after X, so it is added to X, resulting in 10 + 100 = 110. Therefore, XCIII represents 93.

Explanation
LXV is a Roman numeral representation of the number 65. In Roman numerals, L represents 50, X represents 10, and V represents 5. When these values are added together (50 + 10 + 5), the result is 65. Therefore, the correct answer is 65.

Explanation
XXXVIII is a Roman numeral representation for the number 38. In Roman numerals, X represents 10, and V represents 5. When a smaller numeral appears in front of a larger numeral, it is subtracted. So, XXX represents 30 (10+10+10) and V represents 5. When these are added together, it gives us a total of 35. Finally, the additional I (1) represents 1 more, resulting in a total of 36. Therefore, the correct answer is 38.

Explanation
XVI is a Roman numeral representation of the number 16. In Roman numerals, I represents 1, and V represents 5. When a smaller numeral is placed before a larger one, it is subtracted from the larger numeral. Therefore, X (representing 10) is subtracted by I (representing 1), resulting in 9. Adding V (representing 5) to 9 gives us 14. Finally, adding I (representing 1) to 14 gives us 15. Therefore, XVI represents the number 16.

Explanation
XLI is a Roman numeral representation for the number 41. In the Roman numeral system, X represents 10 and L represents 50. When a smaller numeral precedes a larger one, it is subtracted from the larger numeral. In this case, X (10) is subtracted from L (50), resulting in 40, and I (1) is added to it, making the total 41. Therefore, the correct answer is 41.

Explanation
The given number "LXXXIII" is a Roman numeral representation of the number 83. In Roman numerals, "L" represents 50, "XXX" represents 30, and "III" represents 3. When these values are added together (50 + 30 + 3), the result is 83.

Explanation
XCII is a Roman numeral representation of the number 92. In Roman numerals, X represents 10, C represents 100, and I represents 1. When a smaller numeral is placed before a larger numeral, it indicates subtraction. In this case, the smaller numeral I is placed before the larger numeral C, resulting in 100 - 1 = 99. Finally, X is added to the result, resulting in 99 + 10 = 92. Therefore, the correct answer is 92.
