Test: Roman Numerals - Primary 6 MCQ

The Roman numeral L represents the value 50 in the Roman numeral system. In this system, each letter corresponds to a specific value:

• I = 1
• V = 5
• X = 10
• L = 50
• C = 100
• D = 500
• M = 1000

XXIV is calculated by breaking down each Roman numeral from left to right. The breakdown is as follows:

• The first X represents 10.
• The second X adds another 10, making it 20.
• The IV at the end stands for 4 (since I is subtracted from V).

Adding these together:

• 10 + 10 + 4 equals 24.

The Roman numeral for 100 is C.

The Roman numeral for 9 is IX because it represents:

• 10 (X) minus 1 (I)

The Roman numeral XL consists of two parts:

• X represents 10.
• L represents 50.

In Roman numerals, when a smaller numeral comes before a larger numeral, we subtract the smaller numeral from the larger one. Therefore:

• XL means 50 - 10 = 40.

Thus, the value of the Roman numeral XL is 40.

The correct answer is A: 40.

LXXIII is broken down as follows:

• L represents 50.
• The first X represents 10.
• The second X also represents 10.
• III represents 3.

Adding these together:

• 50 (L)
• + 10 (X)
• + 10 (X)
• + 3 (III) = 73.

Therefore, LXXIII converts to 73.

The Roman numeral for 500 is D. This is because in the Roman numeral system:

• D stands for 500.
• This corresponds accurately to the given number.

The Roman numeral XC consists of two parts:

• X represents 10.
• C represents 100.

In Roman numerals, if a smaller numeral comes before a larger numeral, we subtract the smaller numeral from the larger one. Therefore:

• XC means 100 - 10 = 90.

Thus, the value of the Roman numeral XC is 90.

The correct answer is A: 90.

The Roman numeral CD is calculated as follows:

• C represents 100
• D represents 500

Since C (100) comes before D (500), we subtract the value of C from D. Therefore:

• CD = 500 - 100 = 400

The Roman numeral for 200 is CC because:

• Each 'C' represents 100
• Together, they add up to 200
