How to Write 12 in Roman Numerals?

12 in Roman numerals is represented as ‘XII’. The first step to convert 12 in Roman numerals is to write it in expanded form as 12 = 10 + 1 + 1. 

Now replace the numbers with Roman numerals: 12 = X + I + I

Therefore, 12 = XII in Roman numerals.

 

Basic Rules of Roman Numerals

• A symbol gets added to itself if repeated.

For Example: III = 3, XXX = 30, CCC = 300 

 

• A symbol can be repeated only 3 times.

  Example: XXX = 30, CC = 200

 

• Some symbols like V (5), L (50), and D (500) are never repeated.

 

• If a smaller symbol comes after a bigger one, we add.

  Example: XI = 10 + 1 = 11

 

• If a smaller symbol precedes a larger one, we subtract.

  Example: IV = 5 – 1 = 4

 

• Symbols V, L, and D are never subtracted.
  
  

• I can be subtracted only from V and X. 
  
  

• X can be subtracted only from L, C, and M.

 

12 in Roman Numerals- Examples

Example 1:  Explain the difference between X (10) and XII (12) in Roman numerals.
Solution:

We know that X in Roman numerals represents 10 and XII represents 12.

To understand the difference, we have to understand how IIX is written:

As per the rule when a smaller symbol comes after a bigger one, we add, i.e., XII = 10 + 1 + 1 = 12

Therefore, 12 in Roman numerals is XII.

Example 2: What is the value of 20 – 12 in Roman numerals?

Solution:

20 = XX, 12 = XII

XX – XII = VIII (8)

Example 3: What is the value of 8 + 4 in Roman numerals?

Solution:

8 in Roman numeral is VIII

4 in Roman numeral is IV

Conclusion

In Roman numerals, 12 is represented as XII. Roman numerals use a combination of letters and specific rules for addition and subtraction to write numbers. By learning these rules and practicing examples, you can easily interpret the Roman numerals in daily life.

Tens = 12 = XII

Number = XII

 

4. What should be subtracted from XX to get XII?

Answer: 

We know that, 

Roman Numerals XX = 20

Roman Numerals XII = 12

As, 20 – 8 = 12
