Olympiad Test: Roman Numbers - 2 - Class 5 MCQ

• They outline and number lists for clear organization.
• They number preliminary pages in books, such as the introduction.
• They identify certain annual sporting events, like the Olympic Games.

The Roman numeral 'D' represents the number 500.

The correct Roman numeral for 40 is XL.

• X stands for 10.
• L stands for 50.
• In Roman numerals, placing a smaller numeral before a larger one means subtraction.
• Therefore, XL means 50 - 10, which equals 40.

In the Roman numeral system, a smaller numeral placed before a larger numeral indicates subtraction.

• This is a key rule for understanding Roman numerals.
• For example, IV means 4, as you subtract 1 from 5.
• Similarly, IX represents 9, meaning you subtract 1 from 10.

Therefore, when a smaller numeral comes before a larger one, you subtract the smaller numeral from the larger numeral.

The Roman numeral 'XII' represents the number 12.

• X stands for 10.
• I stands for 1.
• When placed together, II adds 2 to 10.

Thus, XII equals 12.

Solution:

• L = 50
• XXX = 30
• IV = 4

Therefore, LXXXIV equals 50 + 30 + 4, which is 84.

The Roman numeral CXI represents the number 111. Here's how it breaks down:

• C stands for 100.
• X stands for 10.
• I stands for 1.

Adding these values together gives you 100 + 10 + 1 = 111.

The Roman numeral CI represents:

• C: 100
• I: 1

Therefore, CI equals 100 + 1 = 101.

Solution:

• X = 10
• IV = 4 (since I before V means 1 less than 5)

Therefore, X + IV = 10 + 4 = 14.

Solution:

• MM represents 2,000.
• IV represents 4.
• Therefore, MMIV equals 2,004 (2,000 + 4).

Solution:

• MMMCXXXIV is a Roman numeral.
• It breaks down into: 3000 (MMM), 100 (C), 30 (XXX), and 4 (IV).
• Adding these values gives: 3134.

1. XLIV = 44.
2. X = 10 and L = 50. XL = 50 - 10 (because X is smaller and placed before L)
3. V = 5 and I = 1. IV = 5 - 1 (because I is smaller and placed before V)
4. (50–10)+(5–1)=44.

The Roman numeral CIV represents a number in our decimal system.

• C stands for 100.
• IV stands for 4, as I is 1 and V is 5. The numeral IV indicates 1 less than 5.

Therefore, CIV is equal to 100 + 4, which is 104.

• Roman numerals are based on combinations of letters from the Latin alphabet.
• 'XL' represents 40 because 'X' (10) is before 'L' (50), indicating subtraction.
• 'V' represents 5.
• So, XL (40) + V (5) equals 45.
• Therefore, the Roman numeral 'XLV' is equal to 45.

The number 3,396 can be broken down into its Roman numeral components:

• 3,000 is represented as MMM
• 300 is represented as CCC
• 90 is represented as XC
• 6 is represented as VI

Combining these, 3,396 is MMMCCCXCVI in Roman numerals.

The Roman numeral CXXXIII represents the number 133.

• C stands for 100.
• XXX represents 30 (as X = 10, and there are three Xs).
• III stands for 3 (as I = 1, and there are three Is).

Adding these values together gives:

• 100 + 30 + 3 = 133

• To find the value of the Roman numeral 'LX', which represents 60:
  
  - 'L' stands for 50 in Roman numerals.
  - 'X' stands for 10 in Roman numerals.
  - So, 'LX' is 50 + 10, which equals 60.
  
  Therefore, the Roman numeral 'LX' is equal to 60. The correct answer is C: 60.

The Roman numeral ‘CX’ represents a number in the Roman numeral system.

• The letter C stands for 100.
• The letter X stands for 10.

By adding these values together, the numeral CX equals 110.

Converting 2011 to Roman Numerals

Understanding Roman Numerals:

• Roman numerals use letters to represent numbers.
• The basic symbols are:
  • I = 1
  • V = 5
  • X = 10
  • L = 50
  • C = 100
  • D = 500
  • M = 1000

Rules for combining Roman numerals:

• Repeating a numeral up to three times adds its value.
  • Example: III = 3
• Placing a smaller numeral before a larger one subtracts its value.
  • Example: IV = 4 (5 - 1)
• Placing a smaller numeral after a larger one adds its value.
  • Example: VI = 6 (5 + 1)

Breaking down 2011:

• 2000 = MM
• 10 = X
• 1 = I

Combining the numerals:

• 2011 = MMXI

Therefore, 2011 in Roman numerals is MMXI.

To break down the Roman numeral conversion for 7,192:

1. 7,000 is represented by MMMMMMM (seven M's).
2. 100 is represented by C.
3. 90 is represented by XC.
4. 2 is represented by II.

When combined, this gives: MMMMMMMCXCII.
