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 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 CCCLXVII to represent 367. Here, CCC is 300, LX is 60, 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.
Rule 1: Addition Method
The addition method is used when the smaller number is placed after the larger number. For example, VII → V + I + I → 5 + 1 + 1 = 7.
Rule 2: Repetition Method
To write a large number, certain Roman Numerals can be repeated up to three times. For example, CCC → 100 + 100 + 100 = 300.
Rule 3: Subtraction Method
If a small number precedes 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, CC for 200 instead of CCCC.
Let’s now learn how to write 367 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 367 in Roman numerals using the expansion method.
To write 367 in Roman Numerals, follow the steps:
Step 1: Break the number based on the place value: hundreds, tens, and ones.
For 367, we write it as 300 + 60 + 7.
Step 2: Convert the number into Roman Numerals.
- 300 in Roman Numerals — CCC
- 60 in Roman Numerals — LX
- 7 in Roman Numerals — VII
Step 3: Combine the Roman Numerals together.
Therefore, 367 in Roman Numerals is CCC(300) + LX(60) + VII(7) = CCCLXVII.
When writing a large number into Roman Numerals, we group the number.
To write 367 in Roman Numerals, we group 367 as 300 + 60 + 7.
- 300 in Roman Numerals — CCC
- 60 in Roman Numerals — LX
- 7 in Roman Numerals — VII
So, 367 is written as CCCLXVII in Roman Numerals.
Students 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.
A librarian has CCCLXVII books to organize in VII shelves. How many books will be placed on each shelf?
The number of books on each shelf is LII.
To find the number of books on each shelf, we divide the total number of books by the number of shelves:
CCCLXVII = 367
VII = 7
Therefore, CCCLXVII / VII = 367 / 7 = 52.
52 in Roman numerals can be written as LII.
Calculate the sum of CLXXXIII and CLXXXIV.
The sum of CLXXXIII and CLXXXIV is CCCLXVII.
To find the sum, add the two numbers together:
CLXXXIII = 183
CLXXXIV = 184
183 + 184 = 367
367 in Roman numerals is CCCLXVII.
A historian uncovers CCCLXVII artifacts, but XXVII are duplicates. How many unique artifacts are there?
The number of unique artifacts is CCCXL.
To find the number of unique artifacts, subtract the duplicates from the total:
CCCLXVII = 367
XXVII = 27
367 - 27 = 340
340 in Roman numerals can be written as CCCXL.
Find the difference when CCCLXXVII is subtracted from D.
The difference is CXXIII.
The difference of two numbers is found by subtraction:
D = 500
CCCLXXVII = 377
500 - 377 = 123
123 in Roman numerals can be written as CXXIII.
Write the Roman Numeral for 367 + 99 using the expansion method.
The Roman numeral for 367 + 99 is CDLXVI.
Step 1: First convert the numbers 367 and 99 into Roman numerals:
367 - CCCLXVII
99 - XCIX
Add the numbers together: 367 + 99 = 466
Using expansion method: 466 = 400 + 60 + 6 = CDL + LX + VI = CDLXVI.
