The symbols used include I (1), V (5), X (10), L (50), C (100), D (500), and M (1000). For 949, the Roman numeral is CMXLIX. Here, CM represents 900, XL represents 40, and IX represents 9.

Basic Rules for 949 in Roman Numerals

There are specific rules for writing numbers in Roman Numerals. Let’s discuss these basic rules:

 

Rule 1: Addition Method

This method is used when a smaller numeral is placed after a larger numeral. For example, VI → V + I → 5 + 1 = 6

 

Rule 2: Repetition Method

Certain Roman Numerals can be repeated up to three times to denote a number. For example, III → 3.

 

Rule 3: Subtraction Method

If a smaller numeral precedes a larger numeral, the smaller numeral is subtracted from the larger. For example, IX → X - I → 10 - 1 = 9

 

Rule 4: Limitation Rule

Symbols cannot be repeated more than three times, and some symbols like V, L, and D cannot be repeated. For example, we write 10 as X, not VV.

How to Write 949 in Roman Numerals

Let’s learn how to write 949 in Roman Numerals. There are various methods:

 

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

949 in Roman Numerals by Expansion Method

Using the expansion method, the number is broken down based on place value. Here’s how to write 949 in Roman numerals:

 

Step 1: Break down the number based on place value: 900 + 40 + 9

 

Step 2: Convert each part into Roman Numerals:

  • 900 in Roman Numerals - CM
     
  • 40 in Roman Numerals - XL
     
  • 9 in Roman Numerals - IX

 

Step 3: Combine them: Therefore, 949 in Roman Numerals is CM (900) + XL (40) + IX (9) = CMXLIX

Professor Greenline from BrightChamps

949 in Roman Numerals by Grouping Method

To write 949 in Roman Numerals using the grouping method, we group the numbers: 900 + 40 + 9

 

  • 900 in Roman Numerals - CM
     
  • 40 in Roman Numerals - XL
     
  • 9 in Roman Numerals - IX

 

So, 949 is written as CMXLIX in Roman Numerals.

Problem 1

Convert the Roman numeral CMXLIX to a decimal number.

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

The decimal number for CMXLIX is 949.

Explanation

To convert CMXLIX to a decimal number, we break it down:

CM = 900, XL = 40, IX = 9.

Adding these together gives 900 + 40 + 9 = 949.

Problem 2

An ancient manuscript contains CMXLIX pages. If a reader finishes XLVII pages, how many pages are left?

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

There are DCCCCII pages left.

Explanation

CMXLIX = 949

XLVII = 47

The remaining pages are 949 - 47 = 902.

902 in Roman Numerals is DCCCCII.

Problem 3

Two ancient cities had populations of CDXLVI and DIII people respectively. What is the combined population?

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

The combined population is CMXLIX.

Explanation

CDXLVI = 446

DIII = 503

The combined population is 446 + 503 = 949.

949 in Roman Numerals is CMXLIX.

Problem 4

If a historian finds artifacts from the year DCC and from the year CCXLIX, what is the difference in years between the two?

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

The difference is CDLI years.

Explanation

DCC = 700

CCXLIX = 249

The difference in years is 700 - 249 = 451.

451 in Roman Numerals is CDLI.

Problem 5

A scroll mentions a price of CMXLIX denarii for a precious item. If the item is reduced by CL, what is the new price?

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

The new price is DCCCXCIX denarii.

CMXLIX = 949

CL = 150

The new price is 949 - 150 = 799.

799 in Roman Numerals is DCCCXCIX.
