What is the numerical value of the Roman numeral XVII?

Rationale

XVII represents the numerical value of 17.

The Roman numeral XVII is formed by combining the values of its constituent letters: X (10), V (5), and II (2), which together sum to 17.

A (22) YOUR ANSWER

The value 22 does not correspond to the Roman numeral XVII. In Roman numerals, the combination of letters X (10) and II (2) only contributes to a total of 12, which is far less than 22. Therefore, this choice misrepresents the numeral's value.

B (17) CORRECT

This is the correct answer. The Roman numeral XVII is calculated as follows: X equals 10, V equals 5, and II equals 2. When summed (10 + 5 + 2), they total 17, accurately reflecting the value represented by XVII.

C (48) YOUR ANSWER

The numeral 48 is not represented by XVII. The Roman numeral for 48 would be XLVIII, where XL (40) combines with VIII (8). Thus, 48 does not relate to the components of XVII, making this choice incorrect.

D (57) YOUR ANSWER

The value 57 is also not represented by XVII. The Roman numeral for 57 is LVII, which consists of L (50) and VII (7). As such, this option does not correspond to the value of XVII, which stands at 17.

Conclusion

Roman numerals are structured through the additive values of their letters, and XVII specifically combines to yield the number 17. Incorrect options such as 22, 48, and 57 reflect misunderstandings of the numeral system and its values. Therefore, recognizing that XVII equals 17 is essential for accurate interpretation of Roman numerals.

What is the numerical value of the Roman numeral XVII?
