Roman numerals are a way of expressing numbers using symbols. I, V, X, L, C, D, and M are the symbols used. Roman numerals are used in royal titles, book names, sequences, and more. Here we will be discussing Roman numerals, rules, and examples.
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 Roman numerals. In earlier times, people used fingers, sticks, bones, etc., to count. As life became complex, a standard form was required for counting.
Ancient Romans used the Roman numeral system for counting. I (1), V (5), X (10), L (50), C (100), D (500), and M (1000) are the symbols used for counting.
In Roman numerals, we use DCCLVI to represent 756. Here, D is 500, CC is 200, L is 50, and VI is 6. Let’s learn more about Roman numerals and how to 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 a smaller number is placed after a larger number. For example, VI → V + I → 5 + 1 = 6.
To write a large number, certain Roman numerals can be repeated up to three times. For example, CCC → 300.
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.
Symbols cannot be repeated more than three times, and some symbols like V, L, and D cannot be repeated. For example, we write XXX for 30 and not XXXX.
Let’s now learn how to write 756 in Roman numerals. Follow these methods to write the number in Roman numerals.
In the expansion method, based on place value, the number is broken down. In this section, we will learn how to write 756 in Roman numerals using the expansion method. To write 756 in Roman numerals, follow these steps:
Step 1: Break the number based on place value: hundreds, tens, and ones. For 756, we write it as 700 + 50 + 6.
Step 2: Convert each number into Roman numerals:
Step 3: Combine them into Roman numerals: Therefore, 756 in Roman numerals is DCC (700) + L (50) + VI (6) = DCCLVI.
When writing a large number into Roman numerals, we group the number. To write 756 in Roman numerals, we group 756 as 700 + 50 + 6.
So, 756 is written as DCCLVI in Roman numerals.
Students often make mistakes when writing a number in Roman numerals. To master Roman numerals, we can learn a few common mistakes and ways to avoid them.
Convert the result of DCCLVI divided by IV into Roman numerals.
The result of DCCLVI divided by IV is CLXXXIX.
DCCLVI is 756 in Roman numerals, and IV is 4.
Dividing 756 by 4 gives 189.
The Roman numeral for 189 is CLXXXIX.
A historian found that a manuscript is DCCLVI years old. If the manuscript was discovered in the year MMXXIII, in which year was it originally written?
The manuscript was originally written in the year MCCCLXVII.
To find the original year, subtract the age of the manuscript from the discovery year: 2023 - 756 = 1267.
The Roman numeral for 1267 is MCCCLXVII.
A library has a collection of DCCLVI rare books and decides to donate CDXXVIII of them. How many rare books will remain in the library?
The number of rare books remaining in the library is CCCXXVIII.
Subtract the donated books from the total: 756 - 428 = 328.
The Roman numeral for 328 is CCCXXVIII.
The population of a small town is DCCLVI. If each family has an average of III members, approximately how many families are there in the town?
There are approximately CCLII families in the town.
To find the number of families, divide the total population by the average family size: 756 / 3 = 252.
The Roman numeral for 252 is CCLII.
A mural is planned to be DCCLVI square feet in area. If the mural is rectangular and one side is XIV feet long, what is the length of the other side?
The length of the other side is LIV feet.
Divide the area by the known side length to find the other side: 756 / 14 = 54.
The Roman numeral for 54 is LIV.
