135 in roman numerals

Royal titles, such as Henry I, Henry II, and so on, often use Roman numerals. Have you noticed the names and wondered what these symbols (I and II) represented? Those are the Roman numerals. Earlier, people used fingers, sticks, bones, etc., to count. 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 CXXXV to represent 135, where C is 100, X is 10, 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, CXXXV → C + X + X + V → 100 + 10 + 10 + 5 = 135.

Rule 2: Repetition Method

To write a large number, certain Roman numerals can be repeated up to three times. For example, XXX → 30.

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 is written as VIII, not IIIIIIII.

Let’s now learn how to write 135 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 place value, the number is broken down. In this section, we will learn how to write 135 in Roman numerals using the expansion method.

To write 135 in Roman numerals, follow these steps:

Step 1: Break the number based on place value: hundreds, tens, ones.

For 135, we write it as 100 + 30 + 5.

Step 2: Convert the numbers into Roman numerals:
100 in Roman numerals — C
30 in Roman numerals — XXX
5 in Roman numerals — V

Step 3: Combine the Roman numerals together.

Therefore, 135 in Roman numerals is C (100) + XXX (30) + V (5) = CXXXV.

When writing a large number into Roman numerals, we group the number. To write 135 in Roman numerals, we group 135 as 100 + 30 + 5.

100 in Roman numerals — C
30 in Roman numerals — XXX
5 in Roman numerals — V

So, 135 is written as CXXXV 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 135:

• Addition rule: The addition method is used when a large number is followed by a smaller numeral, where the values are added. For example, CXXXV = C + XXX + V = 100 + 30 + 5 = 135.

• Grouping method: The given numbers are grouped based on their place value and then converted into Roman numerals. For example, 135 = 100 + 30 + 5 = CXXXV.

• Repetition rule: Certain symbols (I, X, C, M) in the Roman numeric system can be repeated only up to three times. For example, XXX = 30 (X is repeated three times to represent the number 30).

• Subtraction rule: If a smaller numeral precedes a larger numeral, it is subtracted from the larger one. For example, IV = 5 - 1 = 4.

• Place value: Roman numerals are often grouped by their place values, like hundreds, tens, and ones, to simplify conversion. For example, 135 is split as 100, 30, and 5, which are C, XXX, and V, respectively.
