Choose the correct option for the decimal expansion of (\frac{221}{650}).
Answer and explanation
Correct answer: It will be non-terminating recurring
Step 1: (221=13\times17) and (650=2\times5^2\times13). Step 2: After cancelling (13), we get (\frac{17}{50}), so the decimal actually terminates. Step 3: Exam tip: This calculation shows the correct decision is terminating, so the right choice should be (A).
