225 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. Earlier people used to count using fingers, sticks, bones, etc. to count earlier. When life became complex, a standard form was required to count. Ancient Romans used the Roman Numeral system to count. I (1), V (5), X (10), L (50), C (100), D (500), and M (1000) are the symbols we use to count.

In Roman Numerals, we use CCXXV to represent 225; here, CC is 200, XX is 20, and V is 5. Let’s learn more about Roman numerals and how we write them.

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, CCXXV → CC + XX + V → 200 + 20 + 5 = 225

Rule 2: Repetition Method

To write a large number, there are certain Roman Numerals that can be repeated up to three times. For example, CCC → 300.

Rule 3: Subtraction Method

If a small number is followed by a large number in Roman Numerals, we subtract the smaller number from the large 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 won't write VV for 10; instead, we use X, and 8 we write as VIII, not IIIIIIII.

Let’s now learn how to write 225 in Roman Numerals. Follow these methods to write the number in Roman Numerals.

• By Expansion Method

• By Grouping Method

In the expansion method, based on the place value, the number is broken down. In this section, we will learn how to write 225 in Roman numerals using the expansion method.

To write 225 in Roman Numerals, follow the steps:

Step 1: The number is broken based on place value. Place values are ones, tens, hundreds, etc. 

For 225, we write it as 200 + 20 + 5

Step 2: Converting the number into Roman Numerals

200 in Roman Numeral — CC

20 in Roman Numeral — XX

5 in Roman Numeral — V

Step 3: Combining them into Roman Numerals together.

Therefore, 225 in Roman Numeral is CC (200) + XX (20) + V (5) = CCXXV

When writing a large number into Roman Numeral, we group the number.

 
To write 225 in Roman Numeral, we group 225 as 200 + 20 + 5

200 in Roman Numeral — CC

20 in Roman Numeral — XX

5 in Roman Numeral — V

So, 225 is written as CCXXV in Roman Numerals.

Roman Numerals follow a certain pattern making them look similar. In this section, we will learn some numbers related to the Roman numeral 225.

CCXXI = 221
CCXXII = 222
CCXXIII = 223
CCXXIV = 224
CCXXV = 225
CCXXVI = 226
CCXXVII = 227
CCXXVIII = 228
CCXXIX = 229

• Addition Rule: The addition method is used when a large number is followed by a smaller numeral, and the values are added. For example, CCXXV = CC + XX + V = 200 + 20 + 5 = 225.

• Grouping Method: Here, the given numbers are grouped based on their place value and then converted into Roman numerals. For example, 225 = 200 + 20 + 5 = CCXXV.

• Repetition Rule: Certain symbols (I, X, C, M) in the Roman numeric system can be repeated only up to three times. For example, CCC = 300 (C is repeated three times to represent the number 300).

• Subtraction Rule: The subtraction method is used when a smaller numeral precedes a larger one to indicate subtraction. For example, IV = 4 (V - I = 5 - 1).

• Limitation Rule: Some symbols like V, L, and D cannot be repeated, and no Roman numeral can be repeated more than three times.
