Math Question from ImageXVII _ 17 Tick the smallest Roman number. XXI XXV XIX 02 XXXIX XVII the larg esMath Question from Image

Answer: XIX

Explanation: The problem involves identifying the smallest Roman numeral from a list. Roman numerals are a numeral system originating from ancient Rome, using combinations of letters from the Latin alphabet: I, V, X, L, C, D, and M. Each letter represents a specific value.

Steps:

1. Convert each Roman numeral to its integer value:

• XXV:
• X = 10, X = 10, V = 5
• Total = 10 + 10 + 5 = 25
• XIX:
• X = 10, I = 1, X = 10
• Total = 10 + (10 – 1) = 19 (since I before X means subtract 1)
• XXXIX:
• X = 10, X = 10, X = 10, I = 1, X = 10
• Total = 10 + 10 + 10 + (10 – 1) = 39
• XLII:
• X = 10, L = 50, I = 1, I = 1
• Total = (50 – 10) + 1 + 1 = 42 (since X before L means subtract 10)

1. Compare the integer values:

• XXV = 25
• XIX = 19
• XXXIX = 39
• XLII = 42

1. Identify the smallest value:

• The smallest integer value is 19, which corresponds to the Roman numeral XIX.

Thus, the smallest Roman numeral is XIX.
