Please tell me the answer. Roman Numeral Do these practice questions in practice copy: See if you can work out these Roman numerals: XXIII XXXV XXIV LXX CLIII CIX Now make these numbers into Roman numerals: 62 140 754 526 29 Try writing the year you were born in Roman numerals!
The Correct Answer and Explanation is:
Let’s break down the Roman numerals and the conversions.
Practice Questions:
- XXIII:
- X = 10
- X = 10
- III = 3
- Total: 10 + 10 + 3 = 23
- XXXV:
- X = 10
- X = 10
- X = 10
- V = 5
- Total: 10 + 10 + 10 + 5 = 35
- XXIV:
- X = 10
- X = 10
- IV = 4 (since I before V means subtract 1 from 5)
- Total: 10 + 10 + 4 = 24
- LXX:
- L = 50
- X = 10
- X = 10
- Total: 50 + 10 + 10 = 70
- CLIII:
- C = 100
- L = 50
- III = 3
- Total: 100 + 50 + 3 = 153
- CIX:
- C = 100
- IX = 9 (since I before X means subtract 1 from 10)
- Total: 100 + 9 = 109
Now, converting numbers to Roman numerals:
- 62:
- 60 = LX
- 2 = II
- Together: LXII
- 140:
- 100 = C
- 40 = XL
- Together: CXL
- 754:
- 700 = DCC
- 50 = L
- 4 = IV
- Together: DCCLIV
- 526:
- 500 = D
- 20 = XX
- 6 = VI
- Together: DXXVI
- 29:
- 20 = XX
- 9 = IX
- Together: XXIX
Year Born in Roman Numerals:
If you were born in 1999, it would be written as:
- 1000 = M
- 900 = CM
- 90 = XC
- 9 = IX
- Together: MCMXCIX
Explanation:
Roman numerals are based on seven symbols:
- I = 1
- V = 5
- X = 10
- L = 50
- C = 100
- D = 500
- M = 1000
The rules are simple:
- If a smaller numeral comes before a larger one (e.g., IV for 4), subtract the smaller numeral.
- If a smaller or equal numeral comes after a larger one, add the values (e.g., VI for 6).
Roman numerals are often used for clocks, book chapters, movie sequels, and other cases where numbers need a traditional feel.
