xxv xxviii xxix vii: Correct Roman Numeral Answer

Roman numerals question: Change 27 into Roman numerals. A. XXVII B. LXXIV C. XXIX D. XXVIII

The correct answer is A. XXVII. The number 27 is written as 20 + 7 in Roman numerals. XX means 20, and VII means 7, so XXVII means 27. This is the key idea behind xxv xxviii xxix vii style questions: split the number into simple Roman numeral parts.

Why XXVII is the correct Roman numeral for 27

XXVII is correct because Roman numerals build many numbers by adding symbols from left to right. X means 10, so XX means 10 + 10 = 20. V means 5, and II means 2. Together, VII means 5 + 1 + 1 = 7.

Put those parts together: XXVII = XX + VII = 20 + 7 = 27. Roman numerals do not use place value the same way ordinary numbers do. Instead, each symbol has a value, and you add or subtract values depending on their order. In XXVII, all smaller symbols come after larger or equal symbols, so the values are added.

Why the other choices are incorrect

B. LXXIV is not correct because L means 50, XX means 20, and IV means 4. So LXXIV equals 50 + 20 + 4 = 74, not 27. This option is much too large because it begins with L.

C. XXIX is not correct because IX means 9. Therefore, XXIX equals 20 + 9 = 29. This is a common trap because XXIX looks close to XXVII, but the ending IX changes the value to 9.

D. XXVIII is not correct because VIII means 8. So XXVIII equals 20 + 8 = 28. This is probably the easiest wrong choice to confuse with the answer because 28 is only one more than 27.

A quick way to solve similar Roman numeral questions

Roman numerals become easier when you memorize the basic symbols first: I = 1, V = 5, X = 10, L = 50. For 27, think “20 plus 7.” Then write 20 as XX and 7 as VII. That gives XXVII.

Use this quick check for similar options: XXV = 25, XXVII = 27, XXVIII = 28, and XXIX = 29. The ending matters most here: VII is 7, VIII is 8, and IX is 9. When you see xxv xxviii xxix vii in a Roman numeral question, compare the final symbols carefully before choosing.
