1. The problem is to simplify a complex fraction, but the exact fraction is not provided. 2. A complex fraction is a fraction where the numerator, denominator, or both contain fractions. 3. To simplify, we find a common denominator for the smaller fractions or multiply numerator and denominator by the least common denominator (LCD) to eliminate the smaller fractions. 4. Since the exact complex fraction is not given, we cannot perform specific simplification steps. 5. Among the options given (12, 1), the simplest form of a complex fraction often reduces to 1 if numerator and denominator are equal. 6. Without the exact fraction, the best guess is Option C: 1, as it is a common simplified result. Final answer: 1
