3 <p>In ancient Rome, letters were used to represent numbers for easy calculation. Fixed letters were used to denote this numeral system. Even today, in many places, Roman numerals are used to denote royalty, book chapter numbers, or clock faces. In this article, we will learn about Roman numerals and their applications.</p>

4 <h2>What is 47 in Roman Numerals?</h2>

5 <p>There are seven basic<a>symbols</a>in the system to represent particular<a>numbers</a>, which are as follows :</p>

6 <ul><li>I - 1 </li>

7 <li>V - 5 </li>

8 <li>X - 10</li>

9 <li>L - 50</li>

10 <li>C - 100</li>

11 <li>D - 500 </li>

12 <li>M - 1000</li>

13 </ul><p>As per these symbols, XLVII represents 47 in Roman numerals. In this numeral system, there is no symbol for zero (0). In this article, we will learn about the numeral XLVII and different methods to represent it. </p>

14 <h2>Basic Rules for Finding XLVII in Roman Numerals</h2>

15 <p><strong>Rule 1: Addition Method -</strong>In the<a>addition</a>method, you will combine different Roman numerals. When a smaller or the same number is placed after the larger number, we will simply add it - XLVII (47) - XL(L(50) - X(10) = 40) + VII (V(5) + I(1) + I(1) = VII (6)) = LVII (47)</p>

16 <p><strong>Rule 2: Repetition Method -</strong>In this method, a Roman Numeral can only be used up to 3 times to get a larger value</p>

17 <p>XL (40) + II(2) = XLII(42) XL (40) + III(3) = XLIII(43) We can’t write XXXX for 40, it's XL (40)</p>

18 <p><strong>Rule 3: Subtraction Method -</strong>From the repetition method, we got to know that a symbol can’t be used more than 3 times, then how will we write 40 ? Here in Roman numerals, we will use the<a>subtraction</a>method. If the smaller numeral is placed before the larger numeral, then you have to subtract the smaller numeral from the larger numeral. For example, in XLVII (47), there are two parts: XL (40) and VII (7). Here, 40 is obtained by subtracting 10 from 50 ie (50(L) - X(10) = 40(XL)) and VII (V + I + I). Which results in XLVII (47) = XL(40) + VII(7)</p>

19 <p><strong>Rule 4: Limitation Rule -</strong>In Roman Numerals we can't repeat a number more than 3 times. After that, we have to use different symbols. Here you will use<a>addition and subtraction</a>methods. For example - we can't write 4 as IIII, instead we write IV (subtraction method subtracting I(1) from V(5) to get IV(4). For 10, we use X. Here, we can't use VV because there are specific letters assigned to the values, for example (V - 5, X- 10, L - 50, C - 100, D - 500, M - 1000) we have to use these symbols for the specific values. These rules make it easy for us to use the numeral system. </p>

20 <h2>How to Write XLVII Roman Numerals?</h2>

21 <p>To write 47 in Roman numerals, we can simply write it as XLVII. It can be done using two methods :</p>

22 <p><strong>Expansion Method:</strong>In this method, we will break the Roman numeral into smaller parts based on their values and then add them. Here,XLVII(47) is made up of 2 parts that are 40 and 7. 40 can be written as XL. 7 can be written as VII. Now if we add it XL (40) + VII(7) = XLVII(47).</p>

23 <p><strong>Grouping method -</strong> We look at the numerals and group them based on the rules of addition, subtraction, and repetition and add them. Example XLVII</p>

24 <p>XL (40), VII - 7 (since X came before L we subtract 10 from 50).</p>

25 <ul><li><strong>Addition rule:</strong>When a smaller numeral is placed after a larger numeral or equal numeral, then it is said to be additive grouping. Example: II = 1 +1 = 2 </li>

26 </ul><ul><li><strong>Subtractive rule:</strong>When a smaller numeral is placed before a larger numeral, then it is said to be subtractive grouping. Example: XL = 50-10 = 40</li>

27 </ul><ul><li><strong>Repetition:</strong>A numeral can be repeated up to 3 times, and not more than that. Example: III = 1+1+1=3, XXX= 10+10+10= 30. </li>
