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.
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 the 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), C (100), D (500), and M (1000) are the symbols we use to count.
In Roman Numerals, we use _X_X_VMMM to represent 28000, here _X_ is 10000, V is 5000, and MMM is 3000. Let’s learn more about Roman numerals and how we write them.
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.
The addition method is used when the smaller number is placed after the larger number. For example, VI → V + I → 5 + 1 = 6
To write a large number, there are certain Roman Numerals that can be repeated three times. III → 3.
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
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 8 we write as VIII, not IIIIIIII.
Let’s now learn how to write 28000 in Roman Numerals. Follow these methods to write the number in Roman Numerals.
In the expansion method, based on the place value, the number is broken down. In this section, we will learn how to write 28000 in Roman numerals using the expansion method. To write 28000 in Roman Numerals, follow the steps,
Step 1: The number is broken based on the place value. Place value that is ones, tens, hundreds, thousands, etc. For 28000, we write it as 20000 + 5000 + 3000
Step 2: Converting the number into Roman Numerals
Step 3: Combining them Roman Numerals together. Therefore, 28000 in Roman Numerals is _X_X_ (20000) + V (5000) + MMM (3000) = _X_X_VMMM
When writing a large number into Roman Numerals, we group the number. To write 28000 in Roman Numerals, we group 28000 as 20000 + 5000 + 3000.
So, 28000 is written as _X_X_VMMM in Roman Numerals.
Students make mistakes when writing a number in Roman Numerals. To master Roman Numerals, we can learn a few common mistakes and the ways to avoid them.
A historian is cataloging ancient artifacts and labels them in groups of XXVIII thousand. If he has collected artifacts from four different sites, how many artifacts are there in total?
There are CXII thousand artifacts in total.
Each group consists of 28,000 artifacts, and there are four such groups.
Therefore, the total number of artifacts is 28,000 × 4 = 112,000.
In Roman numerals, 112,000 can be represented as CXII thousand.
An architect is designing a coliseum that will have seating for XXVIII thousand spectators. If the coliseum is expanded to accommodate twice as many people, what will be the new seating capacity?
The new seating capacity will be LVI thousand.
The original seating capacity is 28,000.
If doubled, the new capacity will be 28,000 × 2 = 56,000.
In Roman numerals, 56,000 can be represented as LVI thousand.
A museum exhibit includes XXVIII thousand-year-old artifacts. If the exhibit adds another set of artifacts that are CC years newer, what is the combined age of the artifacts?
The combined age of the artifacts is XXVIII thousand CC years.
The exhibit currently features artifacts that are 28,000 years old. Adding artifacts that are 200 years newer means the newer artifacts are 27,800 years old.
Therefore, the total combined age is 28,000 + 27,800 = 55,800 years.
In Roman numerals, 55,800 can be expressed as XXVIII thousand CC years.
A collector has a rare coin worth XXVIII thousand dollars. If the coin appreciates by X thousand dollars over a year, what will be its new value?
The new value of the coin will be XXXVIII thousand dollars.
The coin is currently valued at 28,000 dollars. An appreciation of 10,000 dollars will increase its value to 28,000 + 10,000 = 38,000 dollars. In Roman numerals, 38,000 can be expressed as XXXVIII thousand.
A library records show that XXVIII thousand books were borrowed last year. If the borrowing rate increases by a factor of III, how many books are expected to be borrowed this year?
The expected number of books borrowed this year is LXXXIV thousand.
Last year, 28,000 books were borrowed. If the borrowing rate triples, the expected number of books borrowed this year will be 28,000 × 3 = 84,000.
In Roman numerals, 84,000 can be represented as LXXXIV thousand.
