Roman numerals are a system of expressing numbers using symbols. The symbols used are I, V, X, L, C, D, and M. Roman Numerals are used in royal titles, book names, sequences, and more. Here we will be discussing Roman Numerals, rules, and examples.

What is 108 in Roman Numerals?

The royal titles, such as Henry I, Henry II, and so on. Have you noticed the names and wondered what these symbols (I and II) represented? Those are the Roman Numerals. In ancient times, people used to count using fingers, sticks, bones, etc. When life became complex, a standard form was required to count. Ancient Romans used the Roman Numeral system for counting. The symbols are: I (1), V (5), X (10), L (50), C (100), D (500), and M (1000).

In Roman Numerals, we use CVIII to represent 108. Here, C is 100, V is 5, and III is 3. Let’s learn more about Roman Numerals and how we write them.
 

Basic Rules for 108 in Roman Numerals

There are certain basic rules to write a number in Roman Numerals. In this section, let’s discuss some basic rules that need to be remembered when writing a number in Roman Numerals.

Rule 1: Addition Method

The addition method is used when the smaller number is placed after the larger number. For example, CVIII → C + V + III → 100 + 5 + 3 = 108.

Rule 2: Repetition Method

To write a large number, some Roman Numerals can be repeated up to three times. For example, III → 3.

Rule 3: Subtraction Method

If a smaller number precedes a larger number in Roman Numerals, we subtract the smaller number from the larger number. For example, IX → X - I → 10 - 1 = 9.

Rule 4: Limitation Rule

The symbols cannot be repeated more than three times, and some symbols like V, L, and D cannot be repeated. For example, we don't write VV for 10; instead, we use X. For 8, we write VIII, not IIIIIIII.

108 in Roman Numerals by Expansion Method

In the expansion method, based on the place value, the number is broken down. In this section, we will learn how to write 108 in Roman Numerals using the expansion method.

To write 108 in Roman Numerals, follow the steps:

Step 1: Break the number based on place value: Hundreds, Tens, and Ones.

For 108, we write it as 100 + 8.

Step 2: Convert the numbers into Roman Numerals.

- 100 in Roman Numerals — C.
- 8 in Roman Numerals — VIII.

Step 3: Combine the Roman Numerals.

Therefore, 108 in Roman Numerals is C (100) + VIII (8) = CVIII.
 

108 in Roman Numerals by Grouping Method

When writing a large number into Roman Numerals, we group the number. To write 108 in Roman Numerals, we group 108 as 100 + 8.

- 100 in Roman Numerals — C.
- 8 in Roman Numerals — VIII.

So, 108 is written as CVIII in Roman Numerals.
 

Common Mistakes and How to Avoid Them in 108 Roman Numerals

Students often make mistakes when writing a number in Roman Numerals. To master Roman Numerals, we can learn a few common mistakes and ways to avoid them.

Problem 1

A historian is translating an ancient text and finds references to the years CVIII and CXX. Calculate the sum of these years in Roman numerals.

Okay, lets begin

 The sum of CVIII and CXX is CCXXVIII.
 

Explanation

CVIII = 108  


CXX = 120  


108 + 120 = 228  


228 in Roman Numerals is CCXXVIII.
 

Well explained 👍

Problem 2

A museum received a donation of CCCXVI artifacts, which they decided to distribute evenly among their XXVIII display cases. How many artifacts will each display case contain?

Okay, lets begin

Each display case will contain XII artifacts.
 

Explanation

To find the number of artifacts per display case, divide the total number of artifacts by the number of display cases.  


CCCXVI / XXVIII = 316 / 28 = 11.2857, which rounds to 12 artifacts per case.

 
12 in Roman Numerals is XII.

Well explained 👍

Problem 3

Find the difference between CLXV and CVIII.

Okay, lets begin

The difference between CLXV and CVIII is LVII.
 

Explanation

CLXV = 165  


CVIII = 108  


165 - 108 = 57  


57 in Roman Numerals is LVII.

Well explained 👍

Problem 4

A collector has a total of CCCXXVIII coins. After giving away CVIII coins, how many coins does the collector have left?

Okay, lets begin

The collector has CCXX coins left.
 

Explanation

CCCXXVIII = 328  


CVIII = 108  


328 - 108 = 220  


220 in Roman Numerals is CCXX.
 

Well explained 👍

Problem 5

Write the Roman Numeral for 108 + 59 using the expansion method.

Okay, lets begin

The Roman Numeral for 108 + 59 is CLXVII.
 

Explanation

Step 1: Convert the numbers 108 and 59 into Roman numerals.  


108 = CVIII  
59 = LIX  

Add the numbers together: 108 + 59 = 167  


Using the expansion method: 167 = 100 + 50 + 10 + 7 = CLXVII.

FAQs on 108 in Roman Numerals

1.What is 9 in Roman numerals?

IX is 9, as it has smaller numbers preceding larger ones using the subtraction method. That is X - I, which is 10 - 1 = 9.
 

2.How to write 108 in Roman numerals?

Here, larger numbers are followed by smaller ones, so we use the addition method. That is C(100) + V(5) + III(3) = 108. So, CVIII is 108.

3.What is 16 in Roman Numerals?

16 in Roman Numerals is written as XVI.
 

4.Is CVIII a prime number?

No, 108 is not a prime number. It has factors other than 1 and itself, such as 2, 3, 4, 6, 9, 12, 18, 27, 36, and 54.

The multiples of 108 are 108, 216, 324, 432, 540, and so on.
 

Important Glossaries for 108 in Roman Numerals

  • Addition Rule: The addition method is used when a large numeral is followed by a smaller numeral; here, the values are added. For example, CVIII = C + V + III = 100 + 5 + 3 = 108.
     
  • Grouping Method: Here, the given numbers are grouped based on their place value, and then each group is converted into its Roman numerals. For example, 108 = 100 + 8 = CVIII.
     
  • Repetition Rule: Certain symbols (I, X, C, M) in the Roman numeric system can be repeated only up to three times. For example, III = 3 (I is repeated three times to represent the number 3).
     
  • Subtraction Rule: This method is used when a smaller numeral precedes a larger numeral; the smaller numeral is subtracted from the larger one.
     
  • Limitation Rule: Some symbols like V, L, and D cannot be repeated, and symbols cannot be repeated more than three times.
