Which statement is most correct about the decimal expansion of (\frac{1}{2^2\cdot 5^2\cdot 7})?
Answer and explanation
Correct answer: It is non-terminating recurring
Step 1: The denominator has (7), and the numerator (1) cannot cancel it. Step 2: The reduced denominator has (7) besides (2) and (5), so the decimal is non-terminating recurring. Step 3: Having (2) and (5) in the denominator does not guarantee termination.
