304 in Roman Numerals

Professor Greenline Explaining Math Concepts

Roman numerals are a way of expressing numbers using symbols. I, V, X, L, C, D, and M are the symbols we use. Roman Numerals are used in royal titles, book names, sequences, and so on. Here we will be discussing Roman Numerals, rules, and examples.

What is 304 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 CCCIV to represent 304, where CCC is 300 and IV is 4. Let’s learn more about Roman numerals and how we write them.

Basic Rules for 304 in Roman Numerals

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, then it is the addition method. For example, CCCIV → CCC + IV → 300 + 4 = 304

 

Rule 2: Repetition Method

 

To write a large number, there are certain Roman Numerals that can be repeated three times. 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; it is a subtraction method. For example, IV → V - I → 5 - 1 = 4

 

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 VVV for 15; instead, we use XV, and for 8, we write VIII, not IIIIIIII.

How to Write 304 in Roman Numerals

Let’s now learn how to write 304 in Roman Numerals. Follow these methods to write the number in Roman Numerals. 

 

  • By Expansion Method
  • By Grouping Method

304 in Roman Numeral by Expansion Method

In the expansion method, based on the place value, the number is broken down. In this section, we will learn how to write 304 in Roman numerals using the expansion method.

 

To write 304 in Roman Numerals, follow the steps:

 

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

 

For 304, we write it as 300 + 4

 

Step 2: Converting the number into Roman Numerals


300 in Roman Numerals — CCC
4 in Roman Numerals — IV

 

Step 3: Combining them Roman Numerals together.


Therefore, 304 in Roman Numerals is CCC (300) + IV (4) = CCCIV

Professor Greenline from BrightChamps

304 in Roman Numeral by Grouping Method

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


To write 304 in Roman Numerals, we group 304 as 300 + 4.


300 in Roman Numerals — CCC


4 in Roman Numerals — IV

 

So, 304 is written as CCCIV in Roman Numerals.

Green Checkmark Icon Indicating Correct Solutions in This Math Topic

The repetition method can be confusing for beginners as it states that Roman Numerals cannot be repeated more than three times. In contrast, some of the Roman Numerals such as V, L, and D cannot be repeated.

304 in Roman Numerals Examples

Ray, the Character from BrightChamps Explaining Math Concepts

Problem 1

A historian found CCCIV ancient coins and wants to distribute them equally among XVI historians. How many coins will each historian receive?

Ray, the Boy Character from BrightChamps Saying "Let’s Begin"

 Each historian will receive XIX coins.
 

Explanation

To find the number of coins each historian receives, divide the total number of coins by the number of historians.  


CCCIV = 304  


XVI = 16  


Therefore, CCCIV / XVI = 304 / 16 = 19.  


19 in Roman numerals is XIX.

Problem 2

A museum displayed CCCIV artifacts in one exhibition and CXLV artifacts in another. Find the total number of artifacts displayed.

Ray, the Boy Character from BrightChamps Saying "Let’s Begin"

 The total number of artifacts displayed is CDLIX.

Explanation

Add the two numbers to find the total number of artifacts.  


CCCIV = 304  


CXLV = 145  


304 + 145 = 449  


449 in Roman numerals is CDLIX.

Problem 3

An archaeologist has a collection of CCCIV relics. After donating LXXIII relics to a museum, how many relics does the archaeologist have left?

Ray, the Boy Character from BrightChamps Saying "Let’s Begin"

The archaeologist has CCXXXI relics left.
 

Explanation

 Subtract the number of donated relics from the total.

 
CCCIV = 304

 
LXXIII = 73  


304 - 73 = 231  


231 in Roman numerals is CCXXXI.

Problem 4

A scholar needs to calculate the product of CCCIV and II for a research project. What is the result?

Ray, the Boy Character from BrightChamps Saying "Let’s Begin"

The product of CCCIV and II is DCVIII.
 

Explanation

 Multiply the two numbers to find the product.  


CCCIV = 304

 
II = 2  


304 × 2 = 608  


608 in Roman numerals is DCVIII.

Problem 5

Convert 304 to Roman numerals using the expansion method.

Ray, the Boy Character from BrightChamps Saying "Let’s Begin"

 304 in Roman numerals is CCCIV.
 

Explanation

Break down the number into hundreds, tens, and units.  


304 = 300 + 4  


300 = CCC  


4 = IV  


Combine them: 304 = CCCIV.

Important Glossaries for 304 in Roman Numerals

  • Addition rule: The addition method is used when a large number is followed by a smaller numeral; here, the values are added. For example, CCCIV = CCC + IV = 300 + 4 = 304.

 

  • Grouping method: Here, the given number is grouped based on its place value, and then we convert each group into its Roman numerals. For example, 304 = 300 + 4 = CCCIV.

 

  • 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 numeral; here, the smaller numeral is subtracted from the larger one. For example, IV = V - I = 4.

 

  • Place value decomposition: Breaking down a number into its place values (hundreds, tens, and ones) to convert it into Roman Numerals. For example, 304 becomes 300 + 4.
