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.

What is 38 in Roman Numerals?


The royal titles, such as Henry I, Henry II, and so on, use Roman numerals. Have you noticed the names and wondered what these symbols (I and II) represented? Those are Roman numerals. Earlier, people used fingers, sticks, bones, etc., to count. As 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 XXXVIII to represent 38; here, XXX is 30 and VIII is 8. Let’s learn more about Roman numerals and how we write them.

Basic Rules for 38 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. For example, XXXVIII → XXX + VIII → 30 + 8 = 38.

Rule 2: Repetition Method

To write a large number, certain Roman numerals can be repeated up to three times. For example, XXX → 30 (X is repeated three times).

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, IX → X - I → 10 - 1 = 9.

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 VV for 10; instead, we use X, and 8 is written as VIII, not IIIIIIII.

In the expansion method, based on the place value, the number is broken down. In this section, we will learn how to write 38 in Roman numerals using the expansion method.

To write 38 in Roman numerals, follow these steps:

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

For 38, we write it as 30 + 8.


Step 2: Convert the numbers into Roman numerals.


30 in Roman numerals — XXX


8 in Roman numerals — VIII


Step 3: Combine the Roman numerals together.


Therefore, 38 in Roman numerals is XXX (30) + VIII (8) = XXXVIII.

38 in Roman Numerals by Grouping Method

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


To write 38 in Roman numerals, we group 38 as 30 + 8.


30 in Roman numerals — XXX


8 in Roman numerals — VIII


So, 38 is written as XXXVIII in Roman numerals.

Common Mistakes and How to Avoid Them in 38 Roman Numerals

Students make mistakes when writing a number in Roman numerals. To master Roman numerals, we can learn a few common mistakes and ways to avoid them.

Problem 1

A historian has written a manuscript with XXXVIII chapters. If each chapter is divided into II parts, how many parts are there in total?

Okay, lets begin

The total number of parts is LXXVI.

Explanation

The total number of chapters is XXXVIII, which is 38 in Roman numerals. Each chapter is divided into II parts, which is 2 in Roman numerals. Therefore, the total number of parts is 38 × 2 = 76, which is LXXVI in Roman numerals.

Problem 2

A librarian has CLXXX books and wants to arrange them equally in XXXVIII shelves. How many books will each shelf contain?

Okay, lets begin

Each shelf will contain V books.

Explanation

To find the number of books each shelf will have, divide the total number of books by the number of shelves:  


CLXXX = 180  


XXXVIII = 38  


180 ÷ 38 = 4 remainder 28  


Since we want whole books on each shelf, each shelf will contain 4 books, with some left over.

Problem 3

A teacher assigns a project to be completed in LXII days. If a student completes the project in XXXVIII days, how many days early did the student finish?

Okay, lets begin

The student finished the project XXIV days early.

Explanation

LXII = 62 days  


XXXVIII = 38 days  


62 - 38 = 24  


24 in Roman numerals is XXIV.

Problem 4

Calculate the sum of XLIX and XXXVIII.

Okay, lets begin

he sum of XLIX and XXXVIII is LXXXVII.

Explanation

XLIX = 49
