504 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 504 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. 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 DIV to represent 504, where D is 500, IV is 4.

Basic Rules for 504 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, VI → V + I → 5 + 1 = 6

 

Rule 2: Repetition Method

To write larger numbers, certain Roman Numerals can be repeated three times. For example, III → 3.

 

Rule 3: Subtraction Method

If a smaller number is followed by a larger number in Roman Numerals, we subtract the smaller number from the larger number, which is the 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 is written as VIII, not IIIIIIII.

How to Write 504 in Roman Numerals

Let’s now learn how to write 504 in Roman Numerals. Follow these methods to write the number in Roman Numerals.

 

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

504 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 504 in Roman numerals using the expansion method. To write 504 in Roman Numerals, follow the steps:

 

Step 1: Break the number based on the place value. Place values are ones, tens, hundreds, etc. For 504, we write it as 500 + 4

 

Step 2: Converting the numbers into Roman Numerals

 

  • 500 in Roman Numerals - D
     
  • 4 in Roman Numerals - IV

 

Step 3: Combining the Roman Numerals together. Therefore, 504 in Roman Numerals is D + IV = DIV

Professor Greenline from BrightChamps

504 in Roman Numeral by Grouping Method

When writing a large number into Roman Numerals, we group the number. To write 504 in Roman Numerals, we group 504 as 500 + 4

 

  • 500 in Roman Numerals - D
     
  • 4 in Roman Numerals - IV
     

So, 504 is written as DIV in Roman Numerals.

A marathon was completed in DLXIV minutes, and a runner finished XL minutes early. How long did it take the runner to complete the marathon?

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

The runner completed the marathon in DIV minutes.

Explanation

Subtract the early finish time from the total marathon time.

DLXIV = 564

XL = 40

564 - 40 = 524

524 in Roman Numerals is DIV.

Problem 4

An ancient scroll contains DXLV pages, but XII pages are missing. How many pages are present in the scroll?

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

The number of pages present in the scroll is DIV.

Explanation

Subtract the missing pages from the total pages to find the present pages.

DXLV = 545

XII = 12

Problem 5

Write the Roman Numeral for 300 + 204 using the expansion method.

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

The Roman numeral for 300 + 204 is DIV.

Explanation

Step 1: First convert the numbers 300 and 204 into Roman numerals.

300 - CCC

204 - CCIV

Add the numbers together: 300 + 204 = 504

Using the expansion method: 504 = 500 + 4 = DIV.
