46 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 46 in Roman Numerals?

The royal titles, such as Henry I, Henry II, and so on, often use Roman numerals. 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. As life became more complex, a standard form was required for counting. 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 XLVI to represent 46, where XL is 40 (50 - 10) and VI is 6 (5 + 1). Let’s learn more about Roman numerals and how we write them.46 in roman numerals

Basic Rules for 46 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. For example, III → 3.

 

Rule 3: Subtraction Method

 

If a small number is placed before a larger number in Roman numerals, we subtract the smaller number from the larger number. For example, XL → L - X → 50 - 10 = 40.

 

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, and for 8, we write VIII, not IIIIIIII.

How to Write 46 in Roman Numerals

Let’s now learn how to write 46 in Roman numerals. Follow these methods to write the number in Roman numerals.

 

  • By Expansion Method
  • By Grouping Method

46 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 46 in Roman numerals using the expansion method.

 

To write 46 in Roman numerals, follow the steps:

 

Step 1: Break the number based on the place value: tens and ones.

 

For 46, we write it as 40 + 6.

 

Step 2: Convert the numbers into Roman numerals.

 

40 in Roman numerals — XL

 

6 in Roman numerals — VI

 

Step 3: Combine the Roman numerals together.

 

Therefore, 46 in Roman numerals is XL (40) + VI (6) = XLVI.

Professor Greenline from BrightChamps

46 in Roman Numeral by Grouping Method

When writing a large number in Roman numerals, we group the number.

 

To write 46 in Roman numerals, we group 46 as 40 + 6.

 

40 in Roman numerals — XL

 

6 in Roman numerals — VI

 

So, 46 is written as XLVI in Roman numerals.

Errors in the repetition method

Green Checkmark Icon Indicating Correct Solutions in This Math Topic

The repetition method can be confusing for beginners as it states that Roman numerals cannot be repeated more than three times. In contrast, some of the Roman numerals such as V, L, and D cannot be repeated.

46 in Roman Numerals Examples

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

Problem 1

A historian wants to analyze the timeline of events spanning XLVI years. If each significant event is represented by a Roman numeral, how many events would be needed if each event is spaced equally over the timeline and occurs every VI years?

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

The number of events needed is VIII.

Explanation

To find the number of events, divide the total timeline by the spacing of events.  


XLVI = 46  


VI = 6  


46 / 6 = 7.666..., rounding down gives 7 full intervals, but since the first event occurs at year 0, there are VIII events (including the starting point).

Problem 2

A library has XLVI shelves. Each shelf can hold CLX books. How many books can the entire library hold?

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

The total number of books the library can hold is MMCCCLX.

Explanation

To find the total number of books, multiply the number of shelves by the capacity of each shelf.  


XLVI = 46  


CLX = 160  


46 × 160 = 7360

 
7360 in Roman Numerals is MMCCCLX.

Problem 3

A Roman legion consisted of CD soldiers. If a commander wants to divide them into smaller units of XLVI soldiers each, how many complete units can be formed?

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

The number of complete units is VIII.

Explanation

To determine the number of complete units, divide the total number of soldiers by the number of soldiers per unit.  


CD = 400  


XLVI = 46  


400 / 46 ≈ 8.695, rounding down gives 8 complete units.  


Therefore, the number of complete units is VIII.

Problem 4

Calculate the sum of XLVI and XXIV.

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

The sum of XLVI and XXIV is LXX.

Explanation

Sum is the result of adding two numbers.  


XLVI = 46  


XXIV = 24  


46 + 24 = 70  


70 in Roman Numerals is LXX.

Problem 5

What is the Roman numeral for the result of subtracting XLVI from LXXXII?

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

The result of the subtraction in Roman numerals is XXXVI.

Explanation

Subtraction is finding the difference between two numbers.  


LXXXII = 82  


XLVI = 46  


82 - 46 = 36  


36 in Roman Numerals is XXXVI.
