488 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 488 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 CDLXXXVIII to represent 488, here C is 100, D is 500, L is 50, X is 10, and I is 1.

Basic Rules for 488 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, VIII → V + III → 5 + 3 = 8

 

Rule 2: Repetition Method

To write a large number, there are certain Roman Numerals that can be repeated up to three times. III → 3.

 

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, 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 we write as VIII, not IIIIIIII.

How to Write 488 in Roman Numerals

Let’s now learn how to write 488 in Roman Numerals. Follow these methods to write the number in Roman Numerals.

 

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

488 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 488 in Roman numerals using the expansion method. To write 488 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 488, we write it as 400 + 80 + 8

 

Step 2: Converting the number into Roman Numerals

  • 400 in Roman Numeral - CD
     
  • 80 in Roman Numeral - LXXX
     
  • 8 in Roman Numeral - VIII
     

Step 3: Combining the Roman Numerals together. Therefore, 488 in Roman Numeral is CD (400) + LXXX (80) + VIII (8) = CDLXXXVIII

Professor Greenline from BrightChamps

488 in Roman Numeral by Grouping Method

When writing a large number into Roman Numerals, we group the number. To write 488 in Roman Numeral, we group 488 as 400 + 80 + 8

  • 400 in Roman Numeral - CD
     
  • 80 in Roman Numeral - LXXX
     
  • 8 in Roman Numeral - VIII

So, 488 is written as CDLXXXVIII in Roman Numerals.

Problem 1

Calculate the difference between DXL and XLVIII.

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

The difference between DXL and XLVIII is CDXCII.

Explanation

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

DXL = 540

XLVIII = 48

540 - 48 = 492

492 in Roman Numerals can be written as CDXCII.

Problem 2

A historian found CDXC ancient coins and wants to distribute them equally to VIII archaeologists. How many coins will each archaeologist get?

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

Each archaeologist will get LXI coins.

Explanation

To find the number of coins each archaeologist gets, we divide the total number of coins by the number of archaeologists.

CDXC = 490

VIII = 8

490 / 8 = 61

61 in Roman numerals is LXI.

Problem 3

Find the sum of CDL and XXXVIII.

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

The sum of CDL and XXXVIII is CDLXXXVIII.

Explanation

The sum is the result of adding two numbers.

CDL = 450

XXXVIII = 38

450 + 38 = 488

488 in Roman Numerals is CDLXXXVIII.

Problem 4

What is the product of XL and XII?

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

The product of XL and XII is CDLXXX.

Explanation

The product of two numbers is the result of multiplying them.

XL = 40

XII = 12

40 × 12 = 480

480 in Roman Numerals can be written as CDLXXX.

Problem 5

Write the Roman Numeral for 400 + 88 using the expansion method.

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

The Roman numeral for 400 + 88 is CDLXXXVIII.

Explanation

Step 1: Convert the numbers 400 and 88 into Roman numerals.

400 - CD

88 - LXXXVIII

Add the numbers together: 400 + 88 = 488

Using expansion method: 488 = 400 + 50 + 30 + 8 = CDLXXXVIII.

Important Glossaries for 488 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, VIII = V + III = 5 + 3 = 8.
     
  • Grouping method: Here the given numbers are grouped based on their place value and then we convert each group into its Roman numerals. For example, 488 = 400 + 80 + 8 = CDLXXXVIII.
     
  • Repetition rule: Certain symbols (I, X, C, M) in the Roman numeric system can be repeated only up to three times. For example, III = 3 (I is repeated three times to represent the number 3).
     
  • Subtraction rule: The subtraction method is used when a smaller numeral precedes a larger numeral, whose value is subtracted from the larger numeral's value. For example, IX = X(10) - I(1) = 9.
     
  • Place value: Understanding the place value is crucial to breaking down numbers into their Roman numeral components, such as 488 = 400 (CD) + 80 (LXXX) + 8 (VIII).
