728 in Roman Numerals

The royal titles, such as Henry I, Henry II, and so on, use Roman Numerals. Have you noticed the names and wondered what these symbols (I and II) represented?

Those are the Roman Numerals. Earlier, people used fingers, sticks, bones, etc., to count. When life became complex, a standard form was required for counting. 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 used to count.

In Roman Numerals, we use DCCXXVIII to represent 728. Here, D is 500, C is 100, X is 10, and VIII is 8. 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 the smaller number is placed after the larger number. For example, DCCXXVIII → D + C + C + X + X + V + I + I + I → 500 + 100 + 100 + 10 + 10 + 5 + 1 + 1 + 1 = 728

Rule 2: Repetition Method

To write a large number, certain Roman Numerals can be repeated up to three times. For example, 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. 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 for 8, we write VIII, not IIIIIIII.

Let’s now learn how to write 728 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 728 in Roman numerals using the expansion method.

To write 728 in Roman Numerals, follow the steps:

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

For 728, we write it as 700 + 20 + 8  

Step 2: Converting the number into Roman Numerals  

 700 in Roman Numerals — DCC  
 20 in Roman Numerals — XX  
 8 in Roman Numerals — VIII  

Step 3: Combine the Roman Numerals together.  

Therefore, 728 in Roman Numerals is DCC (700) + XX (20) + VIII (8) = DCCXXVIII

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

To write 728 in Roman Numerals, we group 728 as 700 + 20 + 8  

700 in Roman Numerals — DCC  
20 in Roman Numerals — XX  
8 in Roman Numerals — VIII  

So, 728 is written as DCCXXVIII 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 728.

• Addition rule: The addition method is used when a large number is followed by a smaller numeral; here, the values are added. For example, DCCXXVIII = D + C + C + X + X + V + I + I + I = 728.

• Grouping method: The given numbers are grouped based on their place value and then converted into Roman numerals. For example, 728 = 700 + 20 + 8 = DCCXXVIII.

• 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 one; the smaller value is subtracted from the larger. For example, IX = X - I = 9.

• Limitation rule: Symbols cannot be repeated more than three times, and V, L, and D cannot be repeated. For example, 10 is written as X, not VV.
