How to write Roman numerals from 1 to 50

Roman numerals 1 to 50 can be written by breaking down the number into tens and units and then applying the addition and subtraction rules of Roman numerals. Using this method, we can construct any Roman numeral from 1 to 50.

For example,

  • 28 is written as XXVIII

28 = 10 + 10 + 5 + 1 + 1 + 1 = X + X + X + V + I + I + I = XXVIII

  • 39 is written as XXXIX

39 = 10 + 10 + 10 + (10 - 1) = X + X + X + (X - I) = XXXIX

  • 45 is written as XLV

45 = (50-10) + 5 = (L - X) + V = XLV

Rules for writing Roman numerals from 1 to 50.

  • Subtraction rule: When a smaller numeral precedes a bigger numeral, subtract the smaller value.
    Example: XLI = (50-10) + 1 = 41

  • Addition rule: When a bigger numeral precedes a smaller numeral, the values are added.
    Example: XVI = 10 + 5 + 1 = 16; X > V > I

  • When a symbol is repeated successively, the values are added
    Example: III = 1 + 1 + 1 =3

  • The same symbol cannot be repeated more than three times in succession. Symbols V, L, and D cannot be repeated.

Solved Examples On Roman Numerals from 1 to 50

Example 1: Convert 44 into Roman numerals.
Answer: Break down the number to its components.
44 = (50 - 10) + (5 - 1)
Now replace each number with Roman numerals.
(50 - 10) + (5 - 1) = (L - X) + (V - I) = XLIV.

Example 2: Convert 31 into Roman numerals.
Answer: Break down the number to its components.
31 = 10 + 10 + 10 + 1
Now replace each number with Roman numerals.
31 = 10 + 10 + 10 + 1 = X + X + X + I = XXXI

Example 3: XVIII in Roman numerals is equal to _______.
Answer: XVIII = 10 + 5 + 1 + 1 + 1 = 18

Example 4: Simplify XV + IX
Answer: XV = 10 + 5 = 15 and IX = (10 - 1) = 9
XV + IX = 15 + 9 = 24
XV + IX = XXIV

Example 5: Simplify VI × III
Answer: VI = 5 + 1 = 6 and III = 1 + 1 + 1 = 3
VI × III = 6 × 3 = 18 = XVIII
VI × III = XVIII
