68 in Roman Numerals

Professor Greenline Explaining Math Concepts

Roman numerals are a way of expressing numbers using symbols. The symbols used are I, V, X, L, C, D, and M. Roman numerals are used in royal titles, book names, sequences, and more. Here we will be discussing Roman numerals, their rules, and examples.

What is 68 in Roman Numerals?

Royal titles, such as Henry I, Henry II, and so on, often use Roman numerals. Have you noticed the symbols (I and II) and wondered what they represent? Those are Roman numerals.

 

In ancient times, people used fingers, sticks, bones, etc., to count. As life became more complex, a standard form was required for counting. Ancient Romans used the Roman numeral system for this purpose. I (1), V (5), X (10), L (50), C (100), D (500), and M (1000) are the symbols used in this system.

 

In Roman numerals, we use LXVIII to represent 68, where L is 50, X is 10, and VIII is 8. Let’s learn more about Roman numerals and how we write them.

Basic Rules for 68 in Roman Numerals

There are certain basic rules to writing a number in Roman numerals. In this section, let’s discuss some basic rules that need to be remembered.

 

Rule 1: Addition Method

 

The addition method is used when a smaller number is placed after a larger number. For example, LXVIII → L + X + V + I + I + I → 50 + 10 + 5 + 1 + 1 + 1 = 68

 

Rule 2: Repetition Method

 

To write larger numbers, certain Roman numerals can be repeated up to three times. For example, VIII → 8.

 

Rule 3: Subtraction Method

 

If a smaller number precedes a larger number in Roman numerals, we subtract the smaller number from the larger number. For example, IX → X - I → 10 - 1 = 9

 

Rule 4: Limitation Rule

 

Symbols cannot be repeated more than three times, and symbols like V, L, and D cannot be repeated. For example, we won't write VVV for 15; instead, we use XV.

How to Write 68 in Roman Numerals

Let’s learn how to write 68 in Roman numerals using different methods.

 

  • By Expansion Method
  • By Grouping Method
Professor Greenline from BrightChamps

68 in Roman Numeral by Expansion Method

In the expansion method, based on place values, the number is broken down.

 

To write 68 in Roman numerals, follow these steps:

 

Step 1: Break down the number based on place values: tens and ones. 

For 68, we write it as 50 + 10 + 8


Step 2: Convert these numbers into Roman numerals:


            50 in Roman Numerals — L
           10 in Roman Numerals — X
            8 in Roman Numerals — VIII


Step 3: Combine the Roman numerals:


Therefore, 68 in Roman numerals is L (50) + X (10) + VIII (8) = LXVIII

Professor Greenline from BrightChamps

68 in Roman Numeral by Grouping Method

When writing a large number in Roman numerals, we group the number.

 

To write 68 in Roman numerals, we group 68 as 50 + 10 + 8:


50 in Roman Numerals — L
10 in Roman Numerals — X
8 in Roman Numerals — VIII


So, 68 is written as LXVIII in Roman numerals.

Problem 1

A historian wants to distribute CCCXL ancient coins among V collectors. How many coins will each collector receive?

Ray, the Boy Character from BrightChamps Saying "Let’s Begin"

Each collector will receive LXVIII coins.

Explanation

To find out how many coins each collector receives, divide the total number of coins by the number of collectors.  

CCCXL = 340  

V = 5  

Therefore, CCCXL / V = 340 / 5 = 68.  

68 in Roman numerals is LXVIII.

Problem 2

Calculate the sum of XLV and XXIII in Roman numerals.

Ray, the Boy Character from BrightChamps Saying "Let’s Begin"

The sum of XLV and XXIII is LXVIII.  

Explanation

Sum is the result of adding two numbers.  

XLV = 45  

XXIII = 23  

45 + 23 = 68  

68 in Roman Numerals is LXVIII.  

The sum of XLV and XXIII is LXVIII.

Problem 3

A group of archaeologists found CLX relics and decided to divide them into two batches. If the first batch contains XCII relics, how many relics are in the second batch?

Ray, the Boy Character from BrightChamps Saying "Let’s Begin"

The second batch contains LXVIII relics.

Explanation

The difference is the result of subtracting one number from another.
 
CLX = 160  

XCII = 92  

160 - 92 = 68  

68 in Roman numerals is LXVIII.

Problem 4

A scholar is studying ancient texts and finds LXVIII references to a particular event. How would this number be expressed in Roman numerals using an expanded form approach?

Ray, the Boy Character from BrightChamps Saying "Let’s Begin"

LXVIII can be expressed as 50 + 10 + 5 + 3 in Roman numerals.

Explanation

Break down the number 68 into its expanded form using Roman numerals.  

68 = 50 + 10 + 5 + 3  

50 = L  

10 = X  

5 = V  

3 = III  

Therefore, 68 = LXVIII.

Problem 5

Find the product of XXXIV and II in Roman numerals.

Ray, the Boy Character from BrightChamps Saying "Let’s Begin"

The product of XXXIV and II is LXVIII.  

Explanation

The product is the result of multiplying two numbers.  

XXXIV = 34  

II = 2  

34 × 2 = 68  

68 in Roman numerals is LXVIII.  

The product of XXXIV and II is LXVIII.
