7 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 7 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 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), D (100), and M (1000) are the symbols we use to count.

 

In Roman numerals, we use VII to represent 7; here, V is 5 and II is 2. Let’s learn more about Roman numerals and how we write them.

Basic Rules for 7 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, VII → V + II → 5 + 2 = 7.
 

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, we subtract the smaller number from the larger number. 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. For 8, we write as VIII, not IIIIIIII.

How to Write 7 in Roman Numerals

Let’s now learn how to write 7 in Roman numerals. Follow these methods to write the number in Roman numerals.

 

By Expansion Method
By Grouping Method
 

Professor Greenline from BrightChamps

7 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 7 in Roman numerals using the expansion method.
 

To write 7 in Roman numerals, follow the steps:

 

Step 1: Break the number based on place value, which is ones, tens, hundreds, etc.
 

For 7, we write it as 5 + 2.


Step 2: Converting the number into Roman numerals

5 in Roman numeral — V
2 in Roman numeral — II

Step 3: Combining the Roman numerals together.

Therefore, 7 in Roman numeral is V (5) + II (2) = VII.
 

Professor Greenline from BrightChamps

7 in Roman Numeral by Grouping Method

When writing a number in Roman numerals, we group the number. To write 7 in Roman numerals, we group 7 as 5 + 2.


5 in Roman numeral — V
2 in Roman numeral — II


So, 7 is written as VII in Roman numerals.

Problem 1

A historian is cataloging ancient artifacts and finds VII amulets in one site and XV amulets in another. How many amulets are there in total?

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

The total number of amulets is XXII.
 

Explanation

To find the total, we add the number of amulets from both sites.

VII = 7
XV = 15
7 + 15 = 22

22 in Roman Numerals is XXII.

Problem 2

A treasure chest contains XLII coins. If a pirate decides to split the coins equally among VII crew members, how many coins does each crew member receive?

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

Each crew member receives VI coins.

Explanation

To determine how many coins each crew member receives, we divide the total number of coins by the number of crew members.


XLII = 42
VII = 7
42 / 7 = 6


6 in Roman Numerals is VI.

Problem 3

A collector has a set of XXVIII vintage watches. If the collector decides to display them in groups of VII, how many groups can be formed?

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

The number of groups that can be formed is IV.

Explanation

To find the number of groups, divide the total number of watches by the group size.

XXVIII = 28
VII = 7
28 / 7 = 4

4 in Roman Numerals is IV.

Problem 4

A merchant sells VII baskets of fruit. Each basket contains IX apples. How many apples does the merchant sell in total?

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

The merchant sells LXIII apples in total.

Explanation

To find the total number of apples sold, multiply the number of baskets by the number of apples per basket.


VII = 7
IX = 9
7 × 9 = 63

63 in Roman Numerals is LXIII.

Problem 5

Write the Roman Numeral for 7 multiplied by 3 using the expansion method.

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

The Roman numeral for 7 multiplied by 3 is XXI.

Explanation

First convert the number 7 into Roman numerals


7 - VII

 

Multiply the number: 7 × 3 = 21


Using expansion method: 21 = 10 + 10 + 1 = XXI
