Let’s break down the Roman numeral “DCXVII” into its constituent parts and convert it to a number:

• D represents 500.
• C represents 100.
• X represents 10.
• VII represents 5 + 1 + 1, which is 7.

Now, let’s add these values together:

500 (D) + 100 (C) + 10 (X) + 7 (VII) = 517

So, “DCXVII” in Roman numerals is equivalent to the number 517.

If you want to learn how to convert a whole number to Roman numerals, here are some basic rules:

1. Start with the largest Roman numeral that is less than or equal to the number.
2. Write down that Roman numeral.
3. Subtract its value from the number.
4. Repeat the process with the remainder until you have accounted for the entire number.

For example, to convert 517 to Roman numerals:

• Start with the largest Roman numeral less than or equal to 517, which is 500 (D).
• Write down “D.”
• Subtract 500 from 517, leaving us with 17.
• Now, the largest Roman numeral less than or equal to 17 is 10 (X).
• Write down “X.”
• Subtract 10 from 17, leaving us with 7.
• The largest Roman numeral less than or equal to 7 is 5 (V).
• Write down “V.”
• Subtract 5 from 7, leaving us with 2.
• Finally, the largest Roman numeral less than or equal to 2 is 1 (I).
• Write down “II” (two “I” numerals).

Combine these Roman numerals: D + X + V + II = DCXVII, which is 517.

That’s how you convert a whole number to Roman numerals.
