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 298 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. 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 CCXCVIII to represent 298. Here, C is 100, X is 10, V is 5, and I is 1. Let’s learn more about Roman numerals and how we write them.
 

Basic Rules for 298 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, VIII → V + III → 5 + 3 = 8

Rule 2: Repetition Method

To write a large number, certain Roman Numerals can be repeated up to three times. For example, CCC → 300.

Rule 3: Subtraction Method

If a small number precedes a large number in Roman Numerals, we subtract the smaller number from the large 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 VV for 10; instead, we use X, and for 8, we write VIII, not IIIIIIII.

298 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 298 in Roman numerals using the expansion method.

To write 298 in Roman Numerals, follow the steps:

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

For 298, we write it as 200 + 90 + 8.

Step 2: Convert the number into Roman Numerals:


- 200 in Roman Numerals — CC
- 90 in Roman Numerals — XC
- 8 in Roman Numerals — VIII

Step 3: Combine the Roman Numerals together.


Therefore, 298 in Roman Numerals is CC (200) + XC (90) + VIII (8) = CCXCVIII.

298 in Roman Numeral by Grouping Method

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


To write 298 in Roman Numerals, we group 298 as 200 + 90 + 8:


- 200 in Roman Numerals — CC
- 90 in Roman Numerals — XC
- 8 in Roman Numerals — VIII

So, 298 is written as CCXCVIII in Roman Numerals.
 

Common Mistakes and How to Avoid Them in 298 Roman Numerals

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

Problem 1

A historian is studying two ancient scrolls, one labeled CXLIX and the other labeled CXLIX. What is the combined age of the scrolls in Roman numerals?

Okay, lets begin

The combined age of the scrolls is CCXCVIII.

Explanation

The scrolls are both labeled as CXLIX, which is 149 in Arabic numerals. The combined age is 149 + 149 = 298. In Roman numerals, 298 is written as CCXCVIII.

Problem 2

During a Roman festival, a total of DCCXCIV coins are to be distributed equally among XXVI participants. How many coins does each participant receive?

Okay, lets begin

Each participant receives XXX.

Explanation

To find out how many coins each participant receives, divide the total number of coins by the number of participants:
DCCXCIV / XXVI = 794 / 26 = 30.5


Since each participant receives a whole number of coins, we round down to XXX, which is 30 in Roman numerals.

Problem 3

Calculate the difference between DCCCXLVI and DXLVIII in Roman numerals.

Okay, lets begin

The difference is CCXCVIII.

Explanation

DCCCXLVI = 846


DXLVIII = 548


The difference is 846 - 548 = 298. In Roman numerals, 298 is written as CCXCVIII.

Problem 4

A Roman architect designed a square plaza with sides of length XVII. What is the perimeter of the plaza in Roman numerals?

Okay, lets begin

The perimeter of the plaza is LXVIII.

Explanation

The perimeter of a square is four times the length of one side. Therefore, 4 × XVII = 4 × 17 = 68. In Roman numerals, 68 is written as LXVIII.
 

Well explained 👍

Problem 5

Write the Roman Numeral for 150 + 148 using the expansion method.

Okay, lets begin

The Roman numeral for 150 + 148 is CCXCVIII.

Explanation

Step 1: Convert the numbers 150 and 148 into Roman numerals


150 - CL
148 - CXLVIII

Step 2: Add the numbers together: 150 + 148 = 298


Using the expansion method: 298 = 200 + 90 + 8 = CC + XC + VIII = CCXCVIII.
