They're all correct!

To fill in the blanks and determine the missing Roman numeral values, we need to understand the Roman numeral system. Here is a breakdown of the basic symbols and their corresponding values:

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

To find the missing Roman numeral values, we can look at the given examples and observe the patterns:

1. 23 = XXIII: The symbol "X" represents 10, and "III" represents 3. Hence, 23 is the combination of "XX" (20) and "III" (3).

2. 44 = XLIV: The symbol "XL" represents 40, and "IV" represents 4. Hence, 44 is the combination of "XL" (40) and "IV" (4).

3. 52 = LII: The symbol "L" represents 50, and "II" represents 2. Hence, 52 is the combination of "L" (50) and "II" (2).

4. 17 = XVII: The symbol "X" represents 10, and "VII" represents 7. Hence, 17 is the combination of "X" (10) and "VII" (7).

5. 68 = LXVIII: The symbol "L" represents 50, "X" represents 10, and "VIII" represents 8. Hence, 68 is the combination of "LX" (60) and "VIII" (8).

6. 99 = XCIX: The symbol "XC" represents 90, and "IX" represents 9. Hence, 99 is the combination of "XC" (90) and "IX" (9).

7. 1,111 = MCXI: The symbol "M" represents 1000, "C" represents 100, and "XI" represents 11. Hence, 1,111 is the combination of "M" (1000), "C" (100), and "XI" (11).

8. 575 = DLXXV: The symbol "D" represents 500, "L" represents 50, and "XXV" represents 25. Hence, 575 is the combination of "DL" (550) and "XXV" (25).

9. 946 = CMXLVI: The symbol "CM" represents 900, "XL" represents 40, and "VI" represents 6. Hence, 946 is the combination of "CM" (900), "XL" (40), and "VI" (6).

Using this pattern, you can now determine the missing Roman numeral symbols in each case.
