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.
The royal titles, such as Henry I, Henry II, and so on, use Roman numerals. Have you noticed these symbols and wondered what they represent?
Those are the Roman numerals. Earlier people used fingers, sticks, bones, etc., to count. When life became more 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 DCCXXVII to represent 727. Here, D is 500, CC is 200, XX is 20, and VII is 7. 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.
The addition method is used when the smaller number is placed after the larger number. For example, DCCXXVII → D + CC + XX + VII → 500 + 200 + 20 + 7 = 727
To write a large number, certain Roman numerals can be repeated up to three times. For example, CCC → 300.
If a small number is followed by a large number in Roman numerals, we subtract the smaller number from the larger number. For example, IV → V - I → 5 - 1 = 4
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 we write 8 as VIII, not IIIIIIII.
Let’s now learn how to write 727 in Roman numerals. Follow these methods to write the number in Roman numerals:
In the expansion method, based on the place value, the number is broken down. In this section, we will learn how to write 727 in Roman numerals using the expansion method.
To write 727 in Roman numerals, follow the steps:
Step 1: Break the number based on place value: hundreds, tens, ones, etc.
For 727, we write it as 700 + 20 + 7
Step 2: Convert each number into Roman numerals:
700 in Roman Numerals — DCC
20 in Roman Numerals — XX
7 in Roman Numerals — VII
Step 3: Combine the Roman numerals together.
Therefore, 727 in Roman numerals is DCC (700) + XX (20) + VII (7) = DCCXXVII
When writing a large number in Roman numerals, we group the number. To write 727 in Roman numerals, we group 727 as 700 + 20 + 7:
700 in Roman numerals — DCC
20 in Roman numerals — XX
7 in Roman numerals — VII
So, 727 is written as DCCXXVII in Roman numerals.
