985 in Roman Numerals

Professor Greenline Explaining Math Concepts

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 985 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 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 CMLXXXV to represent 985. Here, CM is 900, LXXX is 80, and V is 5.

Basic Rules for 985 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, VI → V + I → 5 + 1 = 6

 

Rule 2: Repetition Method

To write a large number, there are certain Roman Numerals that can be repeated up to three times. III → 3.

 

Rule 3: Subtraction Method

If a small number is placed before a large number in Roman Numerals, we subtract the smaller number from the larger number. For example, IV → V - I → 5 - 1 = 4

 

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 it as VIII, not IIIIIIII.

How to Write 985 in Roman Numerals

Let’s now learn how to write 985 in Roman Numerals. Follow these methods to write the number in Roman Numerals.

 

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

985 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 985 in Roman numerals using the expansion method. To write 985 in Roman Numerals, follow these steps:

 

Step 1: Break down the number based on place value. Place values include ones, tens, hundreds, etc. For 985, we write it as 900 + 80 + 5

 

Step 2: Convert the number into Roman Numerals

  • 900 in Roman Numerals - CM
     
  • 80 in Roman Numerals - LXXX
     
  • 5 in Roman Numerals - V

 

Step 3: Combine the Roman Numerals together. Therefore, 985 in Roman Numerals is CM (900) + LXXX (80) + V (5) = CMLXXXV

Professor Greenline from BrightChamps

985 in Roman Numerals by Grouping Method

When writing a large number into Roman Numerals, we group the number. To write 985 in Roman Numerals, we group 985 as 900 + 80 + 5

  • 900 in Roman Numerals - CM
     
  • 80 in Roman Numerals - LXXX
     
  • 5 in Roman Numerals - V

So, 985 is written as CMLXXXV in Roman Numerals.

Problem 1

Calculate the difference between CM and LXXXV.

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

The difference between CM and LXXXV is DCCCXV.

Explanation

CM is 900 and LXXXV is 85. To find the difference, subtract LXXXV from CM: 900 - 85 = 815. 815 in Roman Numerals is written as DCCCXV.

Problem 2

A historian counts DCCCL books in a library and wants to distribute them evenly among XV shelves. How many books will each shelf contain?

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

Each shelf will contain LVII books.

Explanation

To find the number of books per shelf, divide the total number of books by the number of shelves: DCCCL / XV. DCCCL is 850 and XV is 15. 850 / 15 = 56.666, rounded to the nearest whole number is 57. 57 in Roman Numerals is LVII.

Problem 3

Add the Roman numerals CDLXXXII and DIII.

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

The sum of CDLXXXII and DIII is CMLXXXV.

Explanation

CDLXXXII is 482 and DIII is 503. Their sum is 482 + 503 = 985. 985 in Roman Numerals is CMLXXXV.

Problem 4

Multiply the Roman numerals XXV and XXXIX.

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

The product of XXV and XXXIX is CMLXXV.

Explanation

XXV is 25 and XXXIX is 39. Multiply these: 25 × 39 = 975. 975 in Roman Numerals is CMLXXV.

Problem 5

Express the sum of CCCL and DCXXXV using the expansion method.

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

The sum of CCCL and DCXXXV using the expansion method is CMLXXXV.

Explanation

First, convert the numbers into Roman numerals:

CCCL = 350

DCXXXV = 635

Add the numbers together: 350 + 635 = 985

Using the expansion method: 985 = 900 + 80 + 5 = CMLXXXV.

Important Glossaries for 985 in Roman Numerals

  • Addition Rule: The addition method is used when a large number is followed by a smaller numeral, here the values are added. For example, XI = X + I = 10 + 1 = 11.
     
  • Grouping Method: Here, numbers are grouped based on their place value and then converted into Roman numerals. For example, 985 = 900 + 80 + 5 = CMLXXXV.
     
  • Repetition Rule: Certain symbols (I, X, C, M) in the Roman numeric system can be repeated only up to three times. For example, III = 3 (I is repeated three times to represent the number 3).
     
  • Subtraction Rule: When a smaller numeral precedes a larger numeral, the smaller is subtracted from the larger. For example, CM = M - C = 1000 - 100 = 900.
     
  • Limitation Rule: V, L, and D cannot be repeated, and no symbol can be repeated more than three times consecutively.
