363 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 363 in Roman Numerals?

The royal titles, such as Henry I, Henry II, and so on, use Roman Numerals. Have you noticed these 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., but as life became more 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 CCCLXIII to represent 363, where CCC is 300, LX is 60, and III is 3. Let’s learn more about Roman numerals and how we write them.363 in roman numerals

Basic Rules for 363 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. For example, LX → L + X → 50 + 10 = 60

 

Rule 2: Repetition Method

 

To write a large number, there are certain Roman Numerals that can be repeated up to three times. CCC → 300 (C is repeated three times).

 

Rule 3: Subtraction Method

 

If a small number is followed by a large 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

 

The symbols cannot be repeated more than three times, and some symbols like V, L, and D cannot be repeated. For example, instead of VV for 10, we use X, and instead of IIIIIIII for 8, we write VIII.

How to Write 363 in Roman Numerals

Let’s now learn how to write 363 in Roman Numerals. Follow these methods to write the number in Roman Numerals. 


By Expansion Method
By Grouping Method

363 in Roman Numerals 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 363 in Roman numerals using the expansion method.

 

To write 363 in Roman Numerals, follow the steps,

 

Step 1: Break the number based on place value. Place values are ones, tens, hundreds, etc.

 

For 363, we write it as 300 + 60 + 3.


Step 2: Converting the number into Roman Numerals


    300 in Roman Numerals — CCC
    60 in Roman Numerals — LX
    3 in Roman Numerals — III


Step 3: Combining the Roman Numerals together.


    Therefore, 363 in Roman Numerals is CCC (300) + LX (60) + III (3) = CCCLXIII
 

Professor Greenline from BrightChamps

363 in Roman Numerals by Grouping Method

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


To write 363 in Roman Numerals, we group 363 as 300 + 60 + 3.


300 in Roman Numerals — CCC
60 in Roman Numerals — LX
3 in Roman Numerals — III


So, 363 is written as CCCLXIII in Roman Numerals.

Errors in the repetition method
 

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.

Problem 1

Find the quotient when CCCLXIII is divided by III.

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

The quotient of CCCLXIII divided by III is CXXI.
 

Explanation

In numbers, CCCLXIII is 363 and III is 3. The quotient of 363 divided by 3 is 121. 121 in Roman Numerals can be written as CXXI.

Problem 2

A historian cataloged CCCLXIII artifacts and wants to distribute them equally into VI collections. How many artifacts will be in each collection?

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

Each collection will have LX artifacts.

Explanation

To find the number of artifacts per collection, divide the total number of artifacts by the number of collections:


CCCLXIII / VI
CCCLXIII = 363
VI = 6


Therefore, 363 / 6 = 60.5, but since artifacts cannot be split, each collection can only have LX artifacts (60 in Roman numerals).

Problem 3

Find the sum of CLX and CCIII.

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

The sum of CLX and CCIII is CCCLXIII.

Explanation

The sum is the result of adding two numbers.


CLX = 160
CCIII = 203
160 + 203 = 363


363 in Roman Numerals is CCCLXIII. The sum of CLX and CCIII is CCCLXIII.

Problem 4

What is the difference between CCCLXXX and XVII.

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

The difference between CCCLXXX and XVII is CCCLXIII.

Explanation

The difference of two numbers is the value we get when subtracting one number from the other.


CCCLXXX = 380
XVII = 17
380 - 17 = 363


363 in Roman Numerals can be written as CCCLXIII.

Problem 5

Write the Roman Numeral for 200 + 163 using the expansion method.

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

The Roman numeral for 200 + 163 is CCCLXIII.

Explanation

Step 1: First convert the numbers 200 and 163 into Roman numerals.


200 - CC
163 - CLXIII

 

Add the numbers together: 200 + 163 = 363


Using expansion method: 363 = 300 + 60 + 3 = CCCLXIII.
