Aterminating
Bnon-terminating and repeating
Cnon-terminating and non-repeating
Dalways a whole number
Answer & Solution
Correct answer: C. non-terminating and non-repeating
1. Rational numbers give terminating or non-terminating repeating decimals.
2. Irrational numbers give a **non-terminating, non-repeating** decimal expansion.
3. e.g. $\pi = 3.14159\ldots$ never terminates or repeats.
