MCQ
A rational number can be expressed as a terminating decimal if the denominator has the factors :
- A$2$ only
- ✓$2$ or $5$ only
- C$2$ or $3$ only
- D$2, 3$ or $5$ only
✓
Answer
Correct option: B.
$2$ or $5$ only
A rational number can be expressed as a terminating decimal if the denominator has the factors $2$ or $5$ or both.
Any other factors in the denominator yield a non $-$ terminating decimal expansion.
