Open Question

कौन-सा हर सरलतम भिन्न में असांत आवर्ती दशमलव देगा?

Which denominator in a reduced fraction will give a non-terminating recurring decimal?

Explanation opens after your attempt
Correct Answer

D. \(2^4\cdot 5\cdot 23\)

Step 1

Concept

For a non-terminating recurring decimal, the reduced denominator must have a prime factor other than (2) and (5).

In which fraction will exactly two non-repeating decimal digits appear before the recurring part begins?

Explanation opens after your attempt
Correct Answer

B. \(\frac{1}{28}\)

Step 1

Concept

View the denominator in terms of (2), (5), and other factors.

Step 2

Why this answer is correct

\(28=2^2\cdot 7\), so the power (2) of (2) gives a delay of two places before the recurring part starts. The other options give a delay of (1) or a different case.

Step 3

Exam Tip

The delay before repetition is linked to the larger power of (2) and (5). चरण 1: हर को (2), (5) और बाकी गुणनखंडों में देखें। चरण 2: \(28=2^2\cdot 7\), इसलिए (2) की घात (2) आवर्ती भाग शुरू होने से पहले दो स्थानों की देरी देती है। बाकी विकल्पों में देरी (1) या अलग होती है। चरण 3: आवर्ती भाग की देरी (2) और (5) की बड़ी घात से जुड़ती है।

To identify non-terminating non-recurring decimals, look for irrational numbers. चरण 1: परिमेय संख्याओं का दशमलव सांत या असांत आवर्ती होता है। चरण 2: \(\sqrt{5}\) अपरिमेय है, इसलिए इसका दशमलव असांत अनावर्ती होता है। चरण 3: असांत अनावर्ती पहचानने के लिए अपरिमेय संख्याओं को अलग करें।

Open Question

किस भिन्न का दशमलव प्रसार असांत आवर्ती है?

Which fraction has a non-terminating recurring decimal expansion?

Explanation opens after your attempt
Correct Answer

D. \(\frac{26}{195}\)

Step 1

Concept

Reduce each option. \(\frac{45}{90}=\frac{1}{2}\), \(\frac{36}{96}=\frac{3}{8}\), and \(\frac{28}{175}=\frac{4}{25}\), so they terminate.

Step 2

Why this answer is correct

\(\frac{26}{195}=\frac{2}{15}\), and the denominator still has (3), so it is non-terminating recurring.

Step 3

Exam Tip

Reducing every option is the safest method. चरण 1: विकल्पों को सरल करें। \(\frac{45}{90}=\frac{1}{2}\), \(\frac{36}{96}=\frac{3}{8}\), और \(\frac{28}{175}=\frac{4}{25}\) सांत हैं। चरण 2: \(\frac{26}{195}=\frac{2}{15}\), जिसके हर में (3) बचता है, इसलिए यह असांत आवर्ती है। चरण 3: हर विकल्प को सरल करना ही सुरक्षित तरीका है।

Open Question

किस विकल्प में दी गई भिन्न का दशमलव प्रसार असांत आवर्ती है, पर सीधे हर देखकर विद्यार्थी उसे गलत तरीके से सांत मान सकता है?

Which fraction has a non-terminating recurring decimal, though a student may wrongly think it terminates by looking quickly at the denominator?

Explanation opens after your attempt
Correct Answer

C. \(\frac{14}{350}\)

Step 1

Concept

\(\frac{14}{350}=\frac{1}{25}\), so it actually terminates.

Step 2

Why this answer is correct

The other listed fractions also reduce to denominators containing only (2) and (5). Therefore none of them is non-terminating recurring.

Step 3

Exam Tip

If a requested option does not appear, recheck every simplification carefully. चरण 1: \(\frac{14}{350}=\frac{1}{25}\) नहीं, बल्कि \(\frac{14}{350}=\frac{1}{25}\) ही होता है, इसलिए यह सांत है। यहाँ सावधानी से विकल्प जाँचें। चरण 2: बाकी दिए गए सभी विकल्प भी सरलतम रूप में केवल (2) और (5) वाले हर देते हैं। इसलिए कोई भी असांत आवर्ती नहीं है। चरण 3: यदि प्रश्न में ऐसा विकल्प माँगा जाए और न मिले, तो गणना दोबारा जाँचें।

Open Question

\(\frac{1}{6}\), \(\frac{1}{12}\), \(\frac{1}{15}\), \(\frac{1}{30}\) में किसका दशमलव प्रसार आवर्ती भाग शुरू होने से पहले सबसे कम सांत भाग रखता है?

Among \(\frac{1}{6}\), \(\frac{1}{12}\), \(\frac{1}{15}\), and \(\frac{1}{30}\), which has the shortest terminating part before the recurring part starts?

Explanation opens after your attempt
Correct Answer

A. \(\frac{1}{6}\)

Step 1

Concept

A denominator with (3) along with (2) or (5) gives a non-terminating recurring decimal.

Step 2

Why this answer is correct

\(\frac{1}{6}=\frac{1}{2\cdot 3}\), so the recurring part starts earliest. The others have \(2^2\), (5), or \(2\cdot 5\), causing a longer non-repeating start.

Step 3

Exam Tip

In mixed denominators, powers of (2) and (5) show how much the recurring part is delayed. चरण 1: हर में (2) या (5) के साथ (3) होने पर दशमलव असांत आवर्ती होता है। चरण 2: \(\frac{1}{6}=\frac{1}{2\cdot 3}\) में (2) की घात (1) है, इसलिए आवर्ती भाग जल्दी शुरू होता है। दूसरे विकल्पों में \(2^2\), (5), या \(2\cdot 5\) से पहले छोटा सांत भाग बनता है। चरण 3: मिश्रित हर में (2) और (5) की घातें आवर्ती भाग शुरू होने की देरी बताती हैं।

Open Question

असमाप्त आवर्ती दशमलव के बारे में सही कथन कौन-सा है?

Which statement is correct about a non-terminating recurring decimal?

Explanation opens after your attempt
Correct Answer

B. यह परिमेय संख्या को दर्शा सकता हैIt can represent a rational number

Step 1

Concept

A non-terminating recurring decimal has a fixed block repeating.

Step 2

Why this answer is correct

Such a decimal can be written as \(\frac{p}{q}\).

Step 3

Exam Tip

So treating it as irrational is a mistake. चरण 1: असमाप्त आवर्ती दशमलव में कोई निश्चित खंड बार-बार आता है। चरण 2: ऐसा दशमलव \(\frac{p}{q}\) के रूप में लिखा जा सकता है। चरण 3: इसलिए इसे अपरिमेय समझना गलती है।

Open Question

यदि सरलतम भिन्न \(\frac{p}{q}\) का दशमलव असमाप्त आवर्ती है, तो (q) के बारे में सही कथन क्या है?

If a fraction \(\frac{p}{q}\) in lowest form has a non-terminating recurring decimal, what is correct about (q)?

Explanation opens after your attempt
Correct Answer

A. (q) में (2) और (5) के अलावा कोई अभाज्य गुणनखंड होगा(q) will have a prime factor other than (2) and (5)

Step 1

Concept

A non-terminating recurring decimal occurs when the reduced denominator has a prime factor other than (2) and (5).

Step 2

Why this answer is correct

Such a denominator cannot be made into a power of (10).

Step 3

Exam Tip

So always check the prime factors of the denominator. चरण 1: असमाप्त आवर्ती दशमलव तब मिलता है जब सरलतम हर में (2) और (5) के अलावा अभाज्य बचता है। चरण 2: ऐसा हर (10) की घात नहीं बन सकता। चरण 3: इसलिए हर के अभाज्य गुणनखंड जरूर जांचें।

Explanation opens after your attempt
Correct Answer

A. \(\frac{18}{75}\)

Step 1

Concept

\(\frac{18}{75}\) simplifies by (3) to \(\frac{6}{25}\), which is terminating, so it must be checked again.

Step 2

Once a fixed repetition appears, the decimal becomes rational. चरण 1: अपरिमेय दशमलव में न तो समाप्ति होती है और न निश्चित आवर्तन। चरण 2: बदलती हुई लंबाई वाले अंकों से स्थिर आवर्तन नहीं बनता। चरण 3: आवर्तन दिखते ही दशमलव परिमेय की ओर जाता है।

Open Question

कौन-सा विकल्प असांत आवर्ती दशमलव है और इसलिए परिमेय है?

Which option is a non-terminating recurring decimal and hence rational?

Explanation opens after your attempt
Correct Answer

A. \(0.123123123\ldots\)

Step 1

Concept

In \(0.123123123\ldots\), the block (123) repeats.

Step 2

Why this answer is correct

A recurring decimal is rational.

Step 3

Exam Tip

Do not call a decimal irrational just because it is non-terminating; check repetition. चरण 1: \(0.123123123\ldots\) में (123) बार-बार आ रहा है। चरण 2: आवर्ती दशमलव परिमेय होता है। चरण 3: केवल असांत देखकर अपरिमेय न मानें; आवर्तन जरूर जाँचें।

Open Question

किस संख्या का दशमलव प्रसार असांत और अनावर्ती होगा?

Which number will have a non-terminating and non-recurring decimal expansion?

Explanation opens after your attempt
Correct Answer

C. \(\sqrt{17}\)

Step 1

Concept

\(\frac{7}{8}\) and (4.25) are terminating decimals.

Step 2

Why this answer is correct

\(\frac{2}{3}\) is non-terminating recurring. \(\sqrt{17}\) is irrational, so its decimal expansion is non-terminating and non-recurring.

Step 3

Exam Tip

Quickly identify square roots of non-perfect squares. चरण 1: \(\frac{7}{8}\) और (4.25) सांत दशमलव देते हैं। चरण 2: \(\frac{2}{3}\) असांत आवर्ती दशमलव देता है। \(\sqrt{17}\) अपरिमेय है, इसलिए उसका दशमलव असांत अनावर्ती होगा। चरण 3: अपूर्ण वर्ग के वर्गमूल को तुरंत पहचानें।
