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 Roman numerals. In earlier times, people used fingers, sticks, bones, etc., to count. As life became more complex, a standard form was required.
Ancient Romans used the Roman numeral system to count. The symbols used are I (1), V (5), X (10), L (50), C (100), D (500), and M (1000). In Roman numerals, we use CDXCV to represent 495, where CD is 400, XC is 90, and V is 5.
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; then it is the addition method. 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, III → 3.
If a small number precedes a large number in Roman numerals, we subtract the smaller number from the large number. For example, IV → V - I → 5 - 1 = 4.
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.
Let’s now learn how to write 495 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 495 in Roman numerals using the expansion method. To write 495 in Roman numerals, follow these steps:
Step 1: Break down the number based on its place value. Place values include hundreds, tens, and ones. For 495, we write it as 400 + 90 + 5.
Step 2: Convert the numbers into Roman numerals.
Step 3: Combine the Roman numerals together. Therefore, 495 in Roman numerals is CD (400) + XC (90) + V (5) = CDXCV.
When writing large numbers in Roman numerals, we group the numbers. To write 495 in Roman numerals, we group 495 as 400 + 90 + 5.
So, 495 is written as CDXCV in Roman numerals.
Students often make mistakes when writing numbers in Roman numerals. To master Roman numerals, we can learn from common mistakes and ways to avoid them.
If a historian finds CDLXXXV artifacts and discovers X more, how many artifacts are there in total?
The total number of artifacts is CDXCV
To find the total, we add the number of artifacts found initially to the new artifacts discovered.
CDLXXXV = 485
X = 10
485 + 10 = 495
495 in Roman Numerals is CDXCV
A librarian has XLV shelves, each holding XI books. How many books does the librarian have in total?
The librarian has CDXCV books in total.
To find the total number of books, multiply the number of shelves by the number of books each shelf holds.
XLV = 45
XI = 11
45 × 11 = 495
495 in Roman Numerals is CDXCV
A runner completes a marathon and covers CDLXXV meters, and then runs XX more meters. How far did the runner run in total?
The runner ran CDXCV meters in total.
To find the total distance, add the initial distance covered to the additional meters run.
CDLXXV = 475
XX = 20
475 + 20 = 495
495 in Roman Numerals is CDXCV
A sculptor creates a statue weighing CCC kilograms and adds another part weighing CLXV kilograms. What is the total weight of the statue?
The total weight of the statue is CDXCV kilograms.
The total weight is the sum of the initial weight and the additional weight.
CCC = 300
CLXV = 165
300 + 165 = 465
465 + 30 = 495
495 in Roman Numerals is CDXCV
Convert the sum of CD and XCV into Roman numerals using the expansion method.
The sum of CD and XCV is CDXCV
Step 1: Convert each number into Roman numerals
CD = 400
XCV = 95
Step 2: Add the numbers together: 400 + 95 = 495
Using the expansion method: 495 = 400 + 90 + 5 = CDXCV
