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.

What is 148 in Roman Numerals?

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 CXLVIII to represent 148, here C is 100, XL is 40, and VIII is 8. Let’s learn more about Roman numerals and how we write them.

Basic Rules for 148 in Roman Numerals

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, then it is the addition method. For example, VIII → V + I + I + I → 5 + 1 + 1 + 1 = 8

 

Rule 2: Repetition Method

 

To write a large number, there are certain Roman Numerals that can be repeated three times. 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, it is a subtraction method. 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, and 8 we write as VIII not IIIIIIII.

How to Write 148 in Roman Numerals

Let’s now learn how to write 148 in Roman Numerals. Follow these methods to write the number in Roman Numerals.

 

  • By Expansion Method  
  • By Grouping Method

148 in Roman Numeral by Expansion Method

In the expansion method, based on the place value, the number is broken down. In this section, we will learn how to write 148 in Roman numerals using the expansion method.

 

To write 148 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 148, we write it as 100 + 40 + 8  


Step 2: Converting the number into Roman Numerals  


100 in Roman Numeral — C  
40 in Roman Numeral — XL  
8 in Roman Numeral — VIII  


Step 3: Combining them Roman Numerals together.  


Therefore, 148 in Roman Numeral is C (100) + XL (40) + VIII (8) = CXLVIII

148 in Roman Numeral by Grouping Method

When writing a large number into Roman Numeral we group the number.  


To write 148 in Roman Numeral, we group 148 as 100 + 40 + 8  


100 in Roman Numeral — C  
40 in Roman Numeral — XL  
8 in Roman Numeral — VIII  


So, 148 is written as CXLVIII in Roman Numerals.
