What type of decimal expansion will (\frac{35}{2^2\cdot 5\cdot 7^2}) have?
Answer and explanation
Correct answer: Non-terminating recurring
Step 1: (35=5\cdot 7). Step 2: The factor (5) and one (7) cancel, but one (7) remains. The reduced denominator is (2^2\cdot 7). So the decimal is non-terminating recurring. Step 3: After partial cancellation, check what factor remains.
