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.

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.

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

• By Expansion Method
• By Grouping 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

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.

Roman numerals follow a certain pattern, making them look similar. In this section, we will learn some numbers related to the Roman numeral 68:

• Addition Rule: The addition method is used when a larger numeral is followed by a smaller one, and their values are added. For example, LXVIII = L + X + VIII = 50 + 10 + 8 = 68.

• Grouping Method: Numbers are grouped based on their place values and then converted into Roman numerals. For example, 68 = 50 + 10 + 8 = LXVIII.

• Repetition Rule: Certain symbols (I, X, C, M) in the Roman numeral system can be repeated up to three times. For example, VIII = 8 (where I is repeated three times to form 8).

• Subtraction Rule: The subtraction method is used when a smaller numeral precedes a larger one, and the smaller is subtracted from the larger. For example, IX = 10 - 1 = 9.

• Limitation Rule: Symbols like V, L, and D cannot be repeated, and no symbol can be repeated more than three times.
