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 discuss 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 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 CCCXXV to represent 325, where CCC is 300, XX is 20, 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.
Rule 1: Addition Method
The addition method is used when the smaller number is placed after the larger number. For example, CCCXXV → CCC + XX + V → 300 + 20 + 5 = 325.
Rule 2: Repetition Method
To write a large number, certain Roman numerals can be repeated up to three times. For example, CCC → 300 (C is repeated three times).
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, IV → V - I → 5 - 1 = 4.
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 DDD for 1500; instead, we use M and D together as MD.
Let’s now learn how to write 325 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 325 in Roman numerals using the expansion method.
To write 325 in Roman Numerals, follow the steps:
Step 1: The number is broken based on the place value. Place values are ones, tens, hundreds, etc.
For 325, we write it as 300 + 20 + 5.
Step 2: Converting the number into Roman Numerals:
300 in Roman Numerals — CCC
20 in Roman Numerals — XX
5 in Roman Numerals — V
Step 3: Combining them in Roman Numerals together:
Therefore, 325 in Roman Numerals is CCC (300) + XX (20) + V (5) = CCCXXV.
When writing a large number into Roman numerals, we group the number.
To write 325 in Roman numerals, we group 325 as 300 + 20 + 5.
300 in Roman numerals — CCC
20 in Roman numerals — XX
5 in Roman numerals — V
So, 325 is written as CCCXXV 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 historian found CCCXXV ancient coins in a chest and wants to distribute them equally among V archaeologists. How many coins will each archaeologist get?
Each archaeologist will get LXV coins.
To find the number of coins each archaeologist gets, we divide the total number of coins by the number of archaeologists.
CCCXXV = 325
V = 5
Therefore, CCCXXV / V = 325 / 5 = 65.
65 in Roman numerals can be written as LXV.
Find the sum of CLXII and CLXIII.
The sum of CLXII and CLXIII is CCCXXV.
Sum is the result of adding two numbers.
CLXII = 162
CLXIII = 163
162 + 163 = 325
325 in Roman Numerals is CCCXXV.
The sum of CLXII and CLXIII is CCCXXV.
A merchant has CCCXXV apples and wants to allocate them into baskets of XXV apples each. How many full baskets can the merchant make?
The merchant can make XIII full baskets.
To find how many full baskets can be made, divide the total number of apples by the number of apples per basket.
CCCXXV = 325
XXV = 25
Therefore, CCCXXV / XXV = 325 / 25 = 13.
13 in Roman numerals can be written as XIII.
What is the difference between CCCXXV and CLXII?
The difference between CCCXXV and CLXII is CLXIII.
The difference of two numbers is the value we get when subtracting one number from the other.
CCCXXV = 325
CLXII = 162
325 - 162 = 163
163 in Roman Numerals can be written as CLXIII.
Write the Roman Numeral for 200 + 125 using the expansion method.
The Roman numeral for 200 + 125 is CCCXXV.
Step 1: First convert the numbers 200 and 125 into Roman numerals.
200 - CC
125 - CXXV
Add the numbers together: 200 + 125 = 325
Using expansion method: 325 = 300 + 20 + 5 = CCCXXV.
