75 in Roman Numerals

The royal titles, such as Henry I, Henry II, and so on, often use Roman numerals. 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 developed the Roman Numeral system. I (1), V (5), X (10), L (50), C (100), and M (1000) are the symbols we use to count.

In Roman Numerals, we use LXXV to represent 75, here L is 50, X is 10, and V is 5. 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, LXXV → L + X + X + V → 50 + 10 + 10 + 5 = 75

Rule 2: Repetition Method

To write a large number, there are certain Roman Numerals that can be repeated up to three times. XXX → 30.

Rule 3: Subtraction Method

If a small number is placed before a larger number in Roman Numerals, we subtract the smaller number from the larger 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 75 in Roman Numerals. Follow these methods to write the number in Roman Numerals. 

• By Expansion Method
• By Grouping Method

In the expansion method, based on the place value, the number is broken down. In this section, we will learn how to write 75 in Roman numerals using the expansion method.

To write 75 in Roman Numerals, follow the steps:

Step 1: Break down the number based on place value. Place values are ones, tens, hundreds, etc.

For 75, we write it as 50 + 10 + 10 + 5.

Step 2: Converting the number into Roman Numerals:

            50 in Roman Numerals — L
           10 in Roman Numerals — X
            5 in Roman Numerals — V

Step 3: Combine the Roman Numerals together. 

Therefore, 75 in Roman Numerals is L (50) + X (10) + X (10) + V (5) = LXXV

When writing a large number into Roman Numerals, we group the number. 

To write 75 in Roman Numerals, we group 75 as 50 + 10 + 10 + 5.

50 in Roman Numerals — L
10 in Roman Numerals — X
5 in Roman Numerals — V

So, 75 is written as LXXV 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 75:

• Addition rule: The addition method is used when a large number is followed by a smaller numeral; here, the values are added. For example, LXXV = L + X + X + V = 50 + 10 + 10 + 5 = 75.

• Grouping method: Here, the given number is grouped based on its place value and then converted into Roman numerals. For example, 75 = 50 + 10 + 10 + 5 = LXXV.

• Repetition rule: Certain symbols (I, X, C, M) in the Roman numeric system can be repeated only up to three times. For example, XXX = 30 (X is repeated three times to represent 30).

• Subtraction rule: When a smaller numeral precedes a larger one, subtraction is used. For example, XL = L - X = 50 - 10 = 40.

• Limitation rule: Symbols such as V, L, and D cannot be repeated. For example, LL is not used for 100; we use C instead.
