What is 498 in Roman Numerals?

Roman numerals are used in various contexts, such as in royal titles like Henry I, Henry II, etc. You may have seen these symbols and wondered about their meaning. They are Roman Numerals. Ancient people initially counted using fingers, sticks, bones, etc. As life became more complex, a standard counting system was necessary.

 

Ancient Romans developed the Roman Numeral system. The symbols I (1), V (5), X (10), L (50), C (100), D (500), and M (1000) are used for counting. In Roman Numerals, 498 is represented as CDXCIII. Here, CD is 400, XC is 90, and VIII is 8.

Basic Rules for 498 in Roman Numerals

There are certain basic rules to write numbers in Roman Numerals. In this section, let’s discuss the basic rules that need to be remembered when writing numbers in Roman numerals.

 

Rule 1: Addition Method

The addition method is used when a smaller number is placed after a larger number. For example, VIII → V + III → 5 + 3 = 8

 

Rule 2: Repetition Method

Certain Roman Numerals can be repeated up to three times to represent a number. For example, III → 3.

 

Rule 3: Subtraction Method

If a smaller number precedes a larger number, it is subtracted. For example, XC → C - X → 100 - 10 = 90

 

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, 10 is written as X, not VV.

How to Write 498 in Roman Numerals

Let’s learn how to write 498 in Roman Numerals. Follow these methods to convert the number into Roman Numerals:

 

  • By Expansion Method
  • By Grouping Method
Professor Greenline from BrightChamps

498 in Roman Numeral by Expansion Method

In the expansion method, a number is broken down based on its place value. Here, we will learn how to write 498 in Roman numerals using the expansion method. To write 498 in Roman Numerals, follow these steps:

 

Step 1: Break the number based on place value: hundreds, tens, and ones. For 498, we break it as 400 + 90 + 8

 

Step 2: Convert each part into Roman Numerals:

  • 400 in Roman Numerals - CD
     
  • 90 in Roman Numerals - XC
     
  • 8 in Roman Numerals - VIII

 

Step 3: Combine them: Therefore, 498 in Roman Numerals is CD + XC + VIII = CDXCIII

Professor Greenline from BrightChamps

498 in Roman Numeral by Grouping Method

When writing a large number in Roman Numerals, we group the number. For 498, group it as 400 + 90 + 8

  • 400 in Roman Numerals - CD
     
  • 90 in Roman Numerals - XC
     
  • 8 in Roman Numerals - VIII
     

So, 498 is written as CDXCIII in Roman Numerals.

Problem 1

What is the result of dividing CMXCVI by II?

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

The result of dividing CMXCVI by II is CDXCIX.

Explanation

CMXCVI is 996 and II is 2.

Dividing 996 by 2 gives us 498, which is written as CDXCIX in Roman numerals.

Problem 2

A historian is categorizing artifacts into boxes of XLIX items each. If there are MMCCCXLII artifacts, how many full boxes can be filled?

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

The number of full boxes that can be filled is XLVIII.

Explanation

To find how many full boxes can be filled, divide the total number of artifacts by the number of artifacts per box. MMCCCXLII = 2,342

XLIX = 49

2,342 / 49 = 47 full boxes

47 in Roman numerals is XLVII.

Problem 3

Add CDXC and VIII together and express the sum in Roman numerals.

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

The sum of CDXC and VIII is CDXCVIII.

Explanation

CDXC = 490

VIII = 8

Adding them together: 490 + 8 = 498

498 in Roman numerals is CDXCVIII.

Problem 4

What is the difference between D and II?

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

The difference between D and II is CDXCVIII.

Explanation

D is 500 and II is 2.

Subtracting 2 from 500 gives us 498.

498 in Roman numerals is CDXCVIII.

Problem 5

Express 400 + 98 in Roman numerals using the expansion method.

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

The Roman numeral for 400 + 98 is CDXCVIII.

Explanation

Step 1: Convert the numbers to Roman numerals.

400 = CD

98 = XCVIII

Add the numbers together: 400 + 98 = 498

Using the expansion method: 498 = 400 + 90 + 8 = CD + XC + VIII = CDXCVIII.
