109 in Roman Numeral

Roman numerals use alphabets to represent each number. The roman numeral 109 is CIX, where C is 100 and IX is 9.
 

• Addition Method

The values get added when the smaller number follows the larger number.
Example:  LX (60) + III (3) = LXIII (63)
Therefore, 109 in roman numeral is expressed as C (100) + VIX (9) = CIX (109)

• Repetition Method

The repetition method won’t allow the letter to be repeated more than three times.  For example, we can write the roman numeral I repeatedly for 10 times to denote the number 10. For 109, we write a CIX. Where C means 100 and IX is 9

• Subtraction Method

The smaller value is subtracted from the larger number. Example:  5-1 = V - I = IV (4). The number ‘1’ comes after ‘5’ so that I is subtracted from V to get IV (4).

• Limitation Rule

The roman numerals cannot be repeated more than three times. For example, instead of writing ‘IIIIIII’, we write VIII for 8, where V is 5 and III is 3.
 

There are two methods to write the number in ancient form, roman numerals. The methods are:

109 in Roman Numeral by Expansion Method

Here, we break the number into its corresponding place value.

Step 1: We break 109 as 1 in the hundreds place, 0 in the tens place, and 9 in one's place.
Step 2: The numbers in the place value will get converted into roman numerals
Step 3: Join the roman numerals to get the desired number

So, 109 in roman numerals is CIX. Where C is 100 and IX is 9.

CIX in Roman Numerals by Grouping Method

The larger roman numeral gets broken into smaller parts.

For CIX,

C → 100
IX → 9

Add (100 + 9)→109
 

The roman numeral 109→CIX is closely related to CCCIX, CDIX, DIX, and so on.

List of numbers related to the roman numeral CIX are:

• C = 100
• CI = 101
• CII = 102
• CIII = 103
• CIV = 104
• CV = 105
• CVI = 106
• CVII = 107
• CVIII = 108
   

• Roman Numeral: Letter that denotes a number. For example, M denotes 1000

• Grouping Method: Splitting of larger number into smaller sections

• Subtraction Method: Subtracting a letter with low value from a letter with greater value. For example, subtracting X (10) from L (50) to get XL (40)
