Roman numerals are a system for expressing numbers using specific symbols: I, V, X, L, C, D, and M. These numerals have been used in royal titles, book names, sequences, and more. Here, we will discuss Roman numerals, their rules, and provide examples related to the number 48000.
Have you ever wondered about the Roman numerals used in royal titles, like Henry I or Henry II? These symbols represent numbers: I (1), V (5), X (10), L (50), C (100), D (500), and M (1000).
The Roman numeral system, developed by the ancient Romans, is still used today. For 48000, we use the symbols XL (40000) and VIII (8000) combined to form XLVIII with a bar over them to indicate multiplication by 1000, which is XLVIII̅.
Let’s explore Roman numerals and how to write them.
There are basic rules to writing numbers in Roman numerals. Here are some key rules to remember when writing numbers in Roman numerals:
When a smaller number follows a larger number, the values are added. For example, VI → V + I = 5 + 1 = 6.
Certain numerals can be repeated up to three times to represent a value. For example, III = 3.
When a smaller numeral precedes a larger numeral, the smaller is subtracted from the larger. For example, IV → V - I = 5 - 1 = 4.
To multiply a numeral by 1000, a bar is placed over it. For example, V̅ represents 5000.
Now let's learn how to write 48000 in Roman numerals. We can use two methods:
Using the expansion method, numbers are broken down based on place value. Here’s how to write 48000 in Roman numerals using this method:
Step 1: Break down the number into place values: 40000 + 8000.
Step 2: Convert each part into Roman numerals.
Step 3: Combine these values: XL̅ + VIII̅ = XLVIII̅.
When writing a large number as a Roman numeral, we group it. For 48000, we group it as 40000 + 8000.
So, 48000 is written as XLVIII̅ in Roman numerals.
