697 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 697 in Roman Numerals?

Royal titles, such as Henry I, Henry II, and so on, employ 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., to count. 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 DCXCVII to represent 697, where D is 500, C is 100, X is 10, V is 5, and II is 2.

Basic Rules for 697 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, DCXCVII → D + C + X + V + I + I → 500 + 100 + 10 + 5 + 1 + 1 = 697

 

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 followed by a large number in Roman Numerals, we subtract the smaller number from the large number. It is a subtraction method. For example, IX → X - I → 10 - 1 = 9

 

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.

How to Write 697 in Roman Numerals

Let’s now learn how to write 697 in Roman Numerals. Follow these methods to write the number in Roman Numerals.

 

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

697 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 697 in Roman numerals using the expansion method. To write 697 in Roman Numerals, follow the steps:

 

Step 1: Break the number based on the place value. Place value that is ones, tens, hundreds, etc. For 697, we write it as 500 + 100 + 90 + 7.

 

Step 2: Convert the number into Roman Numerals.

  • 500 in Roman Numeral - D
     
  • 100 in Roman Numeral - C
     
  • 90 in Roman Numeral - XC
     
  • 7 in Roman Numeral - VII

 

Step 3: Combine the Roman Numerals together. Therefore, 697 in Roman Numeral is D (500) + C (100) + XC (90) + VII (7) = DCXCVII

Professor Greenline from BrightChamps

697 in Roman Numeral by Grouping Method

When writing a large number into Roman Numerals, we group the number. To write 697 in Roman Numerals, we group 697 as 500 + 100 + 90 + 7.

  • 500 in Roman Numeral - D
     
  • 100 in Roman Numeral - C
     
  • 90 in Roman Numeral - XC
     
  • 7 in Roman Numeral - VII

So, 697 is written as DCXCVII in Roman Numerals.

697 in Roman Numerals Examples

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

Problem 1

A historian finds DCCLXVII ancient coins. How many more coins does he need to have M coins in total?

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

He needs CCCXXXIII more coins.

Explanation

To find how many more coins are needed, subtract the number of coins he currently has from M.

M = 1000

DCCLXVII = 767

1000 - 767 = 233

233 in Roman numerals can be written as CCXXXIII.

Problem 2

A museum has a total of MCM items. They divide these items equally into XXVII sections. How many items are in each section?

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

Each section has LXXIII items.

Explanation

To find the number of items per section, divide the total number of items by the number of sections.

MCM = 1900

XXVII = 27

1900 / 27 = 70 with a remainder, which is approximately 73 items per section.

73 in Roman numerals can be written as LXXIII.

Problem 3

Calculate the total weight if each of the DCLXXXVII artifacts weighs II kilograms.

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

The total weight is MMDCCLXXIV kilograms.

Explanation

To find the total weight, multiply the number of artifacts by the weight of each.

DCLXXXVII = 687

II = 2

687 × 2 = 1374

1374 in Roman numerals is MMDCCLXXIV.

Problem 4

What is the sum of CDL and CCXLVII?

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

The sum of CDL and CCXLVII is DCXCVII.

Explanation

To find the sum, add the two numbers together.

CDL = 450

CCXLVII = 247

450 + 247 = 697

697 in Roman numerals is DCXCVII.

Problem 5

Express the difference between M and CCCIII using Roman numerals.

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

The difference is DCLXVII.

Explanation

Subtract CCCIII from M to find the difference.

M = 1000

CCCIII = 303

1000 - 303 = 697

697 in Roman numerals can be written as DCLXVII.
