975 in Roman Numerals

Professor Greenline Explaining Math Concepts

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 975 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. to count earlier. 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 CMLXXV to represent 975, where CM is 900, L is 50, X is 10, and V is 5.

Basic Rules for 975 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, then it is the addition method. 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 three times. XXX → 30.

 

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, it is a subtraction method. For example, CM → M - C → 1000 - 100 = 900

 

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.

How to Write 975 in Roman Numerals

Let’s now learn how to write 975 in Roman Numerals. Follow these methods to write the number in Roman Numerals.

 

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

975 in Roman Numerals 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 975 in Roman numerals using the expansion method. To write 975 in Roman Numerals, follow the steps,

 

Step 1: The number is broken based on the place value. Place value that is ones, tens, hundreds, etc. For 975, we write it as 900 + 70 + 5

 

Step 2: Converting the number into Roman Numerals

  • 900 in Roman Numerals - CM
     
  • 70 in Roman Numerals - LXX
     
  • 5 in Roman Numerals - V

 

Step 3: Combining the Roman Numerals together. Therefore, 975 in Roman Numerals is CM (900) + LXX (70) + V (5) = CMLXXV

Professor Greenline from BrightChamps

975 in Roman Numerals by Grouping Method

When writing a large number into Roman Numerals we group the number. To write 975 in Roman Numerals, we group 975 as 900 + 70 + 5

  • 900 in Roman Numerals - CM
     
  • 70 in Roman Numerals - LXX
     
  • 5 in Roman Numerals - V

So, 975 is written as CMLXXV in Roman Numerals.

Problem 1

A historian discovers DCCCLXXV ancient coins in a chest and wants to distribute them equally among XXV museums. How many coins will each museum get?

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

Each museum will get XXXV coins.

Explanation

To find the number of coins each museum gets, divide the total number of coins by the number of museums. DCCCLXXV = 875 XXV = 25 Therefore, 875 / 25 = 35. 35 in Roman numerals can be written as XXXV.

Problem 2

Calculate the total distance a marathon runner covers if they run XC miles every day for X days.

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

The total distance covered by the runner is CMXC miles.

Explanation

To find the total distance, multiply the daily distance by the number of days.

XC = 90

X = 10

90 × 10 = 900

900 in Roman numerals is CM. Therefore, the total distance is CMXC miles.

Problem 3

A collector has a set of rare stamps, with each stamp valued at CLXV. If he sells six of these stamps, what is the total value in Roman numerals?

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

The total value is CMXC.

Explanation

To find the total value, multiply the value of one stamp by the number of stamps sold.

CLXV = 165

165 × 6 = 990

990 in Roman numerals is CMXC.

Problem 4

What is the sum of CDXC and CDLXXXV in Roman numerals?

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

The sum of CDXC and CDLXXXV is CMLXXV.

Explanation

Sum is the result of adding two numbers.

CDXC = 490

CDLXXXV = 485

490 + 485 = 975

975 in Roman numerals is CMLXXV.

Problem 5

If a library receives DCCCXLV new books, and it already had CXXX books, how many books does it have now in Roman numerals?

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

The library now has CMLXXV books.

Explanation

To find the total number of books, add the new books to the existing books.

DCCCXLV = 845

CXXX = 130

845 + 130 = 975

975 in Roman numerals is CMLXXV.
