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. 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 CCLX to represent 260, where CC is 200, L is 50, and X is 10. 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, CCLX → CC + L + X → 200 + 50 + 10 = 260.
Rule 2: Repetition Method
To write a large number, there are certain Roman numerals that can be repeated up to three times. For example, CCC → 300.
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, XL → L - X → 50 - 10 = 40.
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 LL for 100; instead, we use C.
Let’s now learn how to write 260 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 260 in Roman numerals using the expansion method.
To write 260 in Roman numerals, follow the steps:
Step 1: The number is broken based on the place value. Place value includes ones, tens, hundreds, etc.
For 260, we write it as 200 + 50 + 10.
Step 2: Converting the number into Roman numerals:
200 in Roman Numerals — CC
50 in Roman Numerals — L
10 in Roman Numerals — X
Step 3: Combining the Roman numerals together.
Therefore, 260 in Roman numerals is CC (200) + L (50) + X (10) = CCLX.
When writing a large number into Roman numerals, we group the number.
To write 260 in Roman numerals, we group 260 as 200 + 50 + 10:
200 in Roman Numerals — CC
50 in Roman Numerals — L
10 in Roman Numerals — X
So, 260 is written as CCLX 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.
A historian is cataloging artifacts and finds two sets labeled CL and CX. Find the total number of artifacts.
The total number of artifacts is CCLX.
To find the total, add the Roman numerals CL and CX. CL = 150 CX = 110 150 + 110 = 260 260 in Roman numerals is CCLX.
A librarian has a collection of books divided into sections of LXX and CXC. How many books are there in total?
The total number of books is CCLX.
Add the number of books in each section.
LXX = 70
CXC = 190
70 + 190 = 260
260 in Roman numerals is CCLX.
A teacher wants to distribute CCLX pencils among XX students equally. How many pencils will each student receive?
Each student will receive XIII pencils.
Divide the total number of pencils by the number of students.
CCLX = 260
XX = 20
260 / 20 = 13
13 in Roman numerals is XIII.
If a marathon runner completes CCX kilometers on the first day and L kilometers on the second day, what is the total distance run?
The total distance run is CCLX kilometers.
Add the distances from both days.
CCX = 210
L = 50
210 + 50 = 260
260 in Roman numerals is CCLX.
Write the Roman Numeral for 260 using the expansion method.
The Roman numeral for 260 is CCLX.
Break down 260 into its components.
260 = 200 + 60 = CCLX
200 in Roman numerals is CC, and 60 is LX.
Therefore, 260 = CCLX.
