Question
The decimal expansion that a rational number cannot have is:
- 0. 25
- $0.25\overline{28}$
- $0.\overline{2528}$
- 0.5030030003...
✓
Answer
- 0.5030030003...
Solution:
The decimal expansion of a rational number is either terminating or non-terminating recurring.
The decimal expansion of 0.5030030003... is non-terminating, non-recurring, which is not a property of a rational number.
Hence, the correct opion is (d).
