Why is the decimal expansion of (\frac{5}{12}) non-terminating recurring?
Answer and explanation
Correct answer: Because (12) has factor (3)
Step 1: (\frac{5}{12}) is already in lowest form. Step 2: (12=2^2\times3), and the factor (3) prevents termination. Step 3: Exam tip: A factor other than (2) or (5) gives a recurring decimal.
