Sure, here are five questions about "Roman Numerals to Numbers" along with their answers:

1. What is the value of the Roman numeral 'XLII' in decimal numbers?

The Roman numeral 'XLII' translates to the decimal number 42. The numeral can be broken down as follows:

• 'XL' = 40 (since 'X' before 'L' means 10 subtracted from 50)
• 'II' = 2

So, (40 + 2 = 42).

2. How do you convert the Roman numeral 'CXCIV' to a decimal number?

The Roman numeral 'CXCIV' translates to the decimal number 194. Here’s the breakdown:

• 'C' = 100
• 'XC' = 90 (since 'X' before 'C' means 10 subtracted from 100)
• 'IV' = 4 (since 'I' before 'V' means 1 subtracted from 5)

Thus, (100 + 90 + 4 = 194).

3. What is the decimal value of the Roman numeral 'MMXXIV'?

The Roman numeral 'MMXXIV' translates to the decimal number 2024. Here's how it breaks down:

• 'M' = 1000
• 'M' = 1000
• 'XX' = 20 (10 + 10)
• 'IV' = 4 (since 'I' before 'V' means 1 subtracted from 5)

So, (1000 + 1000 + 20 + 4 = 2024).

4. How would you convert the Roman numeral 'DCCCXLV' to a number?

The Roman numeral 'DCCCXLV' translates to the decimal number 845. The breakdown is as follows:

• 'D' = 500
• 'CCC' = 300 (100 + 100 + 100)
• 'XL' = 40 (since 'X' before 'L' means 10 subtracted from 50)
• 'V' = 5

So, (500 + 300 + 40 + 5 = 845).

5. What is the number for the Roman numeral 'MCMXCIX'?

The Roman numeral 'MCMXCIX' translates to the decimal number 1999. Here's the breakdown:

• 'M' = 1000
• 'CM' = 900 (since 'C' before 'M' means 100 subtracted from 1000)
• 'XC' = 90 (since 'X' before 'C' means 10 subtracted from 100)
• 'IX' = 9 (since 'I' before 'X' means 1 subtracted from 10)

Thus, (1000 + 900 + 90 + 9 = 1999).
