किस भिन्न का दशमलव सांत है पर दिए गए हर में (31) भी दिखाई देता है?
Which fraction has a terminating decimal even though the given denominator contains (31)?
Explanation opens after your attempt
Correct Answer
A. \(\frac{62}{2^4\cdot 5^3\cdot 31}\)
Concept
Since \(62=2\cdot 31\), the factor (31) cancels and the reduced denominator is \(2^3\cdot 5^3\). If an extra prime appears, check cancellation first.
Why this answer is correct
The correct answer is A. \(\frac{62}{2^4\cdot 5^3\cdot 31}\). Since \(62=2\cdot 31\), the factor (31) cancels and the reduced denominator is \(2^3\cdot 5^3\). If an extra prime appears, check cancellation first.
Exam Tip
\(62=2\cdot 31\) है इसलिए (31) कट जाता है और सरल हर \(2^3\cdot 5^3\) बचता है। अतिरिक्त अभाज्य गुणनखंड दिखे तो पहले कटौती देखें।
