724 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 DCCXXIV to represent 724. Here, D is 500, CC is 200, XX is 20, and IV is 4. Let’s learn more about Roman numerals and how we write them.

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 a smaller number is placed after a larger number. For example, XX → X + X → 10 + 10 = 20.

Rule 2: Repetition Method

To write a large number, certain Roman Numerals can be repeated up to three times. For example, CCC → 300.

Rule 3: Subtraction Method

If a smaller number precedes a larger number in Roman Numerals, we subtract the smaller number from the larger number. 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 VV for 10 instead we use X, and 8 we write as VIII not IIIIIIII.
 

Let’s now learn how to write 724 in Roman Numerals. Follow these methods to write the number in Roman Numerals.

• By Expansion Method  
• By Grouping Method
   

In the expansion method, based on the place value, the number is broken down. In this section, we will learn how to write 724 in Roman numerals using the expansion method.

To write 724 in Roman Numerals, follow these steps:

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

For 724, we write it as 700 + 20 + 4.

Step 2: Converting the numbers into Roman Numerals:

700 in Roman Numerals — DCC
20 in Roman Numerals — XX
4 in Roman Numerals — IV

Step 3: Combine the Roman Numerals together.

Therefore, 724 in Roman Numerals is DCC (700) + XX (20) + IV (4) = DCCXXIV.
 

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

To write 724 in Roman Numerals, we group 724 as 700 + 20 + 4:

700 in Roman Numerals — DCC
20 in Roman Numerals — XX
4 in Roman Numerals — IV

So, 724 is written as DCCXXIV in Roman Numerals.
 

Roman Numerals follow a certain pattern making them look similar. In this section, we will learn some numbers related to the Roman numeral 724.
 

• Addition rule: The addition method is used when a larger number is followed by a smaller numeral, and here the values are added. For example, DCCXXIV = DCC + XX + IV = 724.

• 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, 724 = 700 + 20 + 4 = DCCXXIV.

• 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: A smaller numeral placed before a larger numeral indicates subtraction. For example, IV = 5 - 1 = 4.

• Place value: The numerical value that a digit has by virtue of its position in a number. For example, in 724, the 7 is in the hundreds place, the 2 is in the tens place, and the 4 is in the ones place.
