247 in Roman Numerals

Professor Greenline Explaining Math Concepts

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

What is 247 in Roman Numerals?

Royal titles, such as Henry I, Henry II, and so on, often use Roman Numerals. Have you noticed these symbols and wondered what they represent? Those are Roman Numerals. Earlier societies used fingers, sticks, bones, etc., to count. As life became more complex, a standard form of counting was necessary. 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 CCXLVII to represent 247. Here, CC is 200, XL is 40, and VII is 7. Let’s learn more about Roman numerals and how we write them.

Basic Rules for 247 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 a smaller number is placed after a larger number. For example, VII → V + I + I → 5 + 1 + 1 = 7

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 is followed by a large 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, and for 8, we write VIII, not IIIIIIII.

How to Write 247 in Roman Numerals

Let’s now learn how to write 247 in Roman Numerals. Follow these methods to write the number in Roman Numerals. 

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

247 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 247 in Roman numerals using the expansion method.

To write 247 in Roman Numerals, follow the steps:

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

For 247, we write it as 200 + 40 + 7.

Step 2: Convert the number into Roman Numerals.

 

  •     200 in Roman Numerals - CC
     
  •     40 in Roman Numerals - XL
     
  •     7 in Roman Numerals - VII


Step 3: Combine the Roman Numerals together.
    Therefore, 247 in Roman Numerals is CC (200) + XL (40) + VII (7) = CCXLVII.

247 in Roman Numeral by Grouping Method

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


To write 247 in Roman Numerals, we group 247 as 200 + 40 + 7.

 

  • 200 in Roman Numerals - CC
     
  • 40 in Roman Numerals - XL
     
  • 7 in Roman Numerals - VII

 

So, 247 is written as CCXLVII in Roman Numerals.

247 in Roman Numerals Examples

Ray, the Character from BrightChamps Explaining Math Concepts
Max, the Girl Character from BrightChamps

Problem 1

A historian is cataloging ancient artifacts and finds a collection of CCXLVII relics. If each display case can hold XX relics, how many full display cases can be filled?

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

The number of full display cases that can be filled is XII.

Explanation

 To determine how many full display cases can be filled, divide the total number of relics by the capacity of each display case:
CCXLVII / XX = 247 / 20 = 12 full cases.
12 in Roman numerals is XII.

Problem 2

A math competition awards CCXLVII points to a participant. If the participant scores only half of the maximum points, how many points did they score?

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

The participant scores CXXIII points.
 

Explanation

To find out how many points the participant scores, divide the total points by 2:
CCXLVII = 247.
247 / 2 = 123.
123 in Roman numerals is CXXIII.

Problem 3

A library has CLXXX books on Roman history. They acquire an additional LXVII books. How many books do they now have?

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

The library now has CCXLVII books.

Explanation

Add the number of books initially in the library to the additional books acquired:
CLXXX = 180
LXVII = 67
180 + 67 = 247
247 in Roman numerals is CCXLVII.

Problem 4

A marathon race has CCXLVII participants, and XXVII drop out during the race. How many participants finish the race?

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

CCXX participants finish the race.
 

Explanation

Subtract the number of participants who drop out from the total number:
CCXLVII = 247
XXVII = 27
247 - 27 = 220
220 in Roman numerals is CCXX.

Problem 5

Convert the number of hours in a week to Roman numerals.

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

 CLXVI hours.

Explanation

 There are 24 hours in a day and 7 days in a week:
24 × 7 = 168
168 in Roman numerals can be written as CLXVI.
