\(\frac{1}{192}\), \(\frac{1}{225}\), \(\frac{1}{448}\), \(\frac{1}{350}\) में किसमें आवर्ती भाग से पहले सबसे अधिक अनावर्ती अंक होंगे?
Among \(\frac{1}{192}\), \(\frac{1}{225}\), \(\frac{1}{448}\), and \(\frac{1}{350}\), which has the most non-repeating digits before the recurring part?
Explanation opens after your attempt
Correct Answer
C. \(\frac{1}{448}\)
Concept
\(448=2^6\cdot 7\), so (6) non-repeating digits appear before the recurring part. For comparison, check the larger power of (2) and (5).
Why this answer is correct
The correct answer is C. \(\frac{1}{448}\). \(448=2^6\cdot 7\), so (6) non-repeating digits appear before the recurring part. For comparison, check the larger power of (2) and (5).
Exam Tip
\(448=2^6\cdot 7\) है इसलिए आवर्ती भाग से पहले (6) अनावर्ती अंक आएँगे। तुलना में (2) और (5) की बड़ी घात देखें।
