187 in Roman Numerals

Royal titles, such as Henry I, Henry II, and so on, often use Roman Numerals. Have you noticed these titles and wondered what the symbols (I and II) represented? Those are Roman Numerals. Earlier, people used fingers, sticks, bones, etc., to count. As life became complex, a standard form was required.

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 used to count.

In Roman Numerals, we use CLXXXVII to represent 187, where C is 100, L is 50, XXX is 30, and VII is 7. 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, VII → V + I + I → 5 + 1 + 1 = 7

Rule 2: Repetition Method

To write larger numbers, certain Roman Numerals can be repeated up to three times. For example, XXX → 10 + 10 + 10 = 30.

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

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 for 8, we write VIII, not IIIIIIII.

Let’s now learn how to write 187 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 187 in Roman numerals using the expansion method.

To write 187 in Roman Numerals, follow these steps:

Step 1: Break the number based on place value: hundreds, tens, ones.
For 187, we write it as 100 + 80 + 7.

Step 2: Convert the numbers into Roman Numerals.

100 in Roman Numerals — C
80 in Roman Numerals — LXXX
7 in Roman Numerals — VII

Step 3: Combine the Roman Numerals together.

Therefore, 187 in Roman Numerals is C (100) + LXXX (80) + VII (7) = CLXXXVII.

When writing a large number in Roman Numerals, we group the number.

To write 187 in Roman Numerals, we group 187 as 100 + 80 + 7.

100 in Roman Numerals — C
80 in Roman Numerals — LXXX
7 in Roman Numerals — VII

So, 187 is written as CLXXXVII 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 187.

CLXXXV = 185  
CLXXXVI = 186  
CLXXXVII = 187  
CLXXXVIII = 188  
CLXXXIX = 189  
CXC = 190  

• Addition rule: Used when a larger number is followed by a smaller numeral, adding the values. For example, CLXXXVII = C + LXXX + VII = 100 + 80 + 7 = 187.

• Grouping method: Here, numbers are grouped based on their place value and converted into Roman numerals. For example, 187 = 100 + 80 + 7 = CLXXXVII

• Repetition rule: Certain symbols (I, X, C, M) can be repeated up to three times. For example, XXX = 30 (X is repeated three times).

• Subtraction method: Used when a smaller numeral precedes a larger one, subtracting the smaller from the larger. For example, IX = X - I = 10 - 1 = 9

• Limitation rule: Roman numerals cannot be repeated more than three times, and some symbols such as V, L, and D cannot be repeated.
