How to Write 25 in Roman Numerals?

To represent 25 in Roman numerals, we apply the fundamental Roman symbols:

X = 10

V = 5

Let's decompose 25 as:

10 + 10 + 5 = 25

We represent it in Roman numerals as:

X + X + V = XXV

Hence, 25 in Roman numerals is XXV.

Here, we add symbols by adding their values, which is a common way of representing numbers in Roman numerals using letters.

 

Basic Rules to Write Roman Numerals

• A repeated symbol indicates the addition of its value.

Example: II = 2, XX = 2

• A symbol can be repeated up to 3 times.

Example: XXX = 30, CCC = 30

• Symbols V (5), L (50), and D (500) are not repeated.

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

Example: VI = 5 + 1 = 6

• If a smaller symbol comes before a larger one, we subtract.

Example: IV = 5 - 1 = 4

• Using these rules, we can express any number in Roman numerals properly.

Solved Examples on 25 in Roman Numerals

Example 1: Write the result of XV (15) and X (10) added together using Roman numerals.

Solution:

First, write the values of the Roman numerals: XV = 15, X = 10.

Add the two numbers: 15 + 10 = 25.

Now, convert the result back into Roman numerals. The number 25 in Roman numerals is XXV.

Answer: XV + X = XXV

 

Example 2: What number is to be added to XX (20) in order to obtain XXV?

Solution:

We know XXV = 25 and XX = 20.

To find the missing number, subtract XX from XXV: 25 - 20 = 5.

The number 5 in Roman numerals is V.

So, to get XXV, we need to add V to XX.

Answer: XX + V = XXV

 

Example 3: What is the difference between XXV and X?

Solution:

First, write the values: XXV = 25 and X = 10.

Subtract X from XXV: 25 - 10 = 15.

The number 15 in Roman numerals is XV.

Answer: XXV - X = XV

Conclusion

The Roman numeral for 25 is XXV. By adding X (10) and V (5), we get 25. Learning the rules of Roman numerals guides students in writing and reading numbers appropriately, from small numbers such as 25 (XXV) up to larger numbers.
