Key Rules for Writing Roman Numerals 50 to 100
- L = 50, C = 100, X = 10, V = 5, I = 1
- A smaller symbol before a bigger one is subtracted (e.g., XC = 90 = 100 – 10)
- A smaller or same symbol after a bigger one is added (e.g., LXX = 50 + 10 + 10 = 70)
- Repeating a symbol more than three times is not allowed (use XC for 90, not LXXXX)
- Use only valid combinations: e.g., 99 is XCIX (not IC), 89 is LXXXIX
Step-by-Step Example: Converting Numbers to Roman Numerals
Let’s convert the number 78 to Roman numerals:
1. 78 = 50 + 10 + 10 + 5 + 1 + 1 + 12. 50 is L
3. 10 + 10 is XX
4. 5 + 1 + 1 + 1 is VIII
5. Combine: L + XX + VIII = LXXVIII
Another example: 94
1. 94 = 90 + 42. 90 is XC (100 – 10)
3. 4 is IV
4. Combine: XC + IV = XCIV
Common Mistakes to Avoid
- Writing 90 as LXXXX (correct: XC)
- Using four I’s in a row (the usual limit is 3; 4 is IV)
- Writing 99 as IC (correct: XCIX)
- Repeating X’s more than three times for numbers above 89 (use XC for 90)

FAQs on Roman Numerals 50 to 100: Step-by-Step Chart & Guide
1. What are Roman numerals from 50 to 100?
Roman numerals from 50 to 100 are symbols used in the Roman numeral system to represent numbers without digits. This range mainly uses the letters L (50), X (10), V (5), I (1), and C (100) in various combinations. For example, 50 is L, 60 is LX (50 + 10), and 90 is XC (100 minus 10).
2. How do you write 50, 75, and 100 in Roman numerals?
The numbers 50, 75, and 100 are written as follows in Roman numerals: 50 is L, 75 is LXXV (50 + 10 + 10 + 5), and 100 is C. These follow the basic rules of adding values to form numbers.
3. What is the Roman numeral for 51 and 90?
The Roman numeral for 51 is LI (50 + 1), and for 90, it is XC. The notation XC represents 100 minus 10, which follows the Roman numeral subtraction rule avoiding repeated X's.
4. Are there worksheets for Roman numerals 50 to 100?
Yes, free printable worksheets for Roman numerals 50 to 100 are available to help students practice reading, writing, and converting numbers within this range. These worksheets often include tables, exercises, and conversion practice to aid revision and exam preparation.
5. Where are Roman numerals 50 to 100 used in daily life?
Roman numerals from 50 to 100 commonly appear in clocks, event numbering (like Olympics or Super Bowls), chapter titles in books, movie sequels, and on monuments. Learning their usage connects students to real-world applications and cultural references.
6. Why is 90 written as XC, not LXXXX, in Roman numerals?
The number 90 is written as XC in Roman numerals because of the subtractive notation rule, which states that smaller numerals placed before larger ones are subtracted. Writing 90 as LXXXX (50 + 10 + 10 + 10 + 10) is incorrect and considered a common mistake. Using XC simplifies notation and follows standard Roman numeral rules.
7. Why do students often confuse LXIX with LXXXIX?
Students often confuse LXIX (69) and LXXXIX (89) because both contain multiple X and I characters, and the sequence looks similar. The key difference lies in the placement of I (1) before X (10) in LXIX, representing one less than ten, while LXXXIX includes three X's before I, reflecting eighty-nine. Understanding the Roman numeral formation rules helps avoid such confusion.
8. What are the most common mistakes when converting 50–100 to Roman numerals?
Common mistakes include:
1. Incorrectly repeating numerals more than three times (like writing LXXXX for 90 instead of XC).
2. Misplacing subtractive notation, such as writing IL for 49.
3. Forgetting that L, D, and C cannot be repeated.
4. Confusing IX and XI, or LXIX and LXXXIX.
Practising Roman numeral rules and charts reduces these mistakes.
9. Why should you avoid repeated X's when writing 90 or 99 in Roman numerals?
Repeated X's should be avoided because Roman numerals follow the rule of not repeating any symbol more than three times consecutively. For example, 90 is written as XC (100 minus 10) instead of LXXXX. Similarly, 99 is XCIX, not LXXXXVIIII. Using subtractive notation ensures clarity and adherence to standard rules.
10. How do examiners mark errors in Roman numeral notation?
Examiners typically mark errors when students:
• Use incorrect Roman numerals (e.g., LXXXX for 90).
• Repeat numerals more than allowed.
• Misplace subtractive notation.
• Show inconsistency in notation.
Adhering to Roman numeral formation rules and practising conversion helps students score correctly in exams.
