Roman numerals are the 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. 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., to count earlier. 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 CCLXXII to represent 272, where C is 100, L is 50, X is 10, and I is 1. 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, CCLXXII → C + C + L + X + X + I + I → 100 + 100 + 50 + 10 + 10 + 1 + 1 = 272
Rule 2: Repetition Method
To write a large number, certain Roman Numerals can be repeated up to three times. For example, III → 3.
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, IX → X - I → 10 - 1 = 9
Rule 4: Limitation Rule
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 8 is written as VIII, not IIIIIIII.
Let’s now learn how to write 272 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 272 in Roman numerals using the expansion method.
To write 272 in Roman Numerals, follow the steps:
Step 1: Break the number based on the place value. Place values are ones, tens, hundreds, etc.
For 272, we write it as 200 + 70 + 2
Step 2: Convert the number into Roman Numerals
200 in Roman Numeral — CC
70 in Roman Numeral — LXX
2 in Roman Numeral — II
Step 3: Combine the Roman Numerals together.
Therefore, 272 in Roman Numerals is CC (200) + LXX (70) + II (2) = CCLXXII
When writing a large number into Roman Numerals, we group the number.
To write 272 in Roman Numerals, we group 272 as 200 + 70 + 2
200 in Roman Numeral — CC
70 in Roman Numeral — LXX
2 in Roman Numeral — II
So, 272 is written as CCLXXII 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 the ways to avoid them.
Find the quotient of DXLIV and II.
The quotient of DXLIV and II is CCLXXII.
In Roman numerals, DXLIV is 544 and II is 2. The quotient of DXLIV and II is 544 ÷ 2 = 272. 272 in Roman numerals can be written as CCLXXII.
A historian found a collection of CCLXXII old coins divided equally among IV families. How many coins did each family receive?
Each family received LXVIII coins.
To find the number of coins each family receives, we divide the total number of coins by the number of families. That is CCLXXII / IV.
CCLXXII = 272
IV = 4
Therefore, 272 ÷ 4 = 68.
68 in Roman numerals can be written as LXVIII.
Find the sum of CCLXX and II.
The sum of CCLXX and II is CCLXXII.
The sum is the result of adding two numbers.
CCLXX = 270
II = 2
270 + 2 = 272
272 in Roman Numerals is CCLXXII.
The sum of CCLXX and II is CCLXXII.
What is the difference between CCLXXV and III?
The difference between CCLXXV and III is CCLXXII.
The difference of two numbers is the value we get when subtracting one number from the other.
CCLXXV = 275
III = 3
275 - 3 = 272
272 in Roman Numerals can be written as CCLXXII
Write the Roman Numeral for 200 + 72 using the expansion method.
The Roman numeral for 200 + 72 is CCLXXII.
Step 1: First, convert the numbers 200 and 72 into Roman numerals.
200 - CC
72 - LXXII
Add the numbers together: 200 + 72 = 272.
Using the expansion method: 272 = 200 + 70 + 2 = CCLXXII.
