\(\frac{1}{2^3\cdot 5^4\cdot 19^2}\) के दशमलव में आवर्ती भाग से पहले कितने अनावर्ती अंक आएँगे?

In the decimal expansion of \(\frac{1}{2^3\cdot 5^4\cdot 19^2}\), how many non-repeating digits appear before the recurring part?

Explanation opens after your attempt
Correct Answer

B. (4)

Step 1

Concept

Since \(19^2\) remains, the decimal is non-terminating recurring, and the larger exponent among (2) and (5) is (4). In such questions, separate recurrence from the initial delay.

Step 2

Why this answer is correct

The correct answer is B. (4). Since \(19^2\) remains, the decimal is non-terminating recurring, and the larger exponent among (2) and (5) is (4). In such questions, separate recurrence from the initial delay.

Step 3

Exam Tip

\(19^2\) बचने से दशमलव असांत आवर्ती होगा और (2), (5) की बड़ी घात (4) आरंभिक अनावर्ती भाग देगी। ऐसे प्रश्न में आवर्तीपन और आरंभिक देरी अलग-अलग देखें।

यदि किसी दशमलव में \(0.357357357\ldots\) जैसा स्थिर आवर्ती खंड है, तो वह किस प्रकार की संख्या है?

If a decimal has a fixed repeating block like \(0.357357357\ldots\), what type of number is it?

Explanation opens after your attempt
Correct Answer

A. परिमेय संख्याRational number

Step 1

Concept

Step 2

Why this answer is correct

A fixed recurring decimal can always be written as a rational number.

Step 3

Exam Tip

\(\frac{1}{18}\), \(\frac{1}{45}\), \(\frac{1}{72}\), \(\frac{1}{90}\) में किसमें आवर्ती भाग से पहले सबसे अधिक अनावर्ती अंक आएँगे?

Among \(\frac{1}{18}\), \(\frac{1}{45}\), \(\frac{1}{72}\), and \(\frac{1}{90}\), which has the most non-repeating digits before the recurring part?

Explanation opens after your attempt
Correct Answer

C. \(\frac{1}{72}\)

Step 1

Concept

The larger power of (2) or (5) in the denominator tells the delay before the recurring part starts.

Step 2

Why this answer is correct

\(72=2^3\cdot 3^2\), so it has a delay of (3) places. The others have larger exponent (1) or (2).

Step 3

Exam Tip

Understand the initial non-repeating part in non-terminating recurring decimals. चरण 1: हर में (2) और (5) की बड़ी घात आवर्ती भाग शुरू होने की देरी बताती है। चरण 2: \(72=2^3\cdot 3^2\), इसलिए इसमें देरी (3) स्थानों की होगी। बाकी में बड़ी घात (1) या (2) है। चरण 3: असांत आवर्ती दशमलव में आरंभिक अनावर्ती भाग को भी समझें।

किस भिन्न में आवर्ती भाग शुरू होने से पहले ठीक दो अनावर्ती दशमलव अंक आएँगे?

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।

किस भिन्न में आवर्ती भाग दशमलव बिंदु के तुरंत बाद शुरू होगा?

In which fraction will the repeating part start immediately after the decimal point?

Explanation opens after your attempt
Correct Answer

A. \(\frac{1}{7}\)

Step 1

Concept

The denominator of \(\frac{1}{7}\) has no factor (2) or (5), so the repeating part starts immediately.

Step 2

Why this answer is correct

(14), (28), and (35) also contain (2) or (5), so a non-repeating part comes first.

Step 3

Exam Tip

Factors (2) or (5) can delay the start of the recurring part. चरण 1: \(\frac{1}{7}\) के हर में (2) या (5) नहीं है, इसलिए आवर्ती भाग तुरंत शुरू होता है। चरण 2: (14), (28), और (35) में (2) या (5) भी हैं, इसलिए आवर्ती भाग से पहले कुछ सांत भाग आता है। चरण 3: हर में (2) या (5) की उपस्थिति आवर्ती भाग को आगे खिसका सकती है।

किसी परिमेय संख्या का हर सरलतम रूप में \(2^3 \times 5^2 \times 7\) है। उसके दशमलव प्रसार के बारे में सही कथन चुनिए।

The denominator of a rational number in lowest form is \(2^3 \times 5^2 \times 7\). Choose the correct statement about its decimal expansion.

Explanation opens after your attempt
Correct Answer

A. असांत आवर्तीNon-terminating repeating

Step 1

Concept

A rational number has a terminating decimal only when the denominator in lowest form has prime factors only (2) and (5).

Step 2

Why this answer is correct

Here the denominator also contains (7), so the decimal will not terminate, but since the number is rational, it will repeat.

Step 3

Exam Tip

In exams, always reduce the fraction first and then check the prime factors of the denominator. चरण 1: परिमेय संख्या का दशमलव प्रसार तभी सांत होता है जब सरलतम रूप में हर के अभाज्य गुणनखंड केवल (2) और (5) हों। चरण 2: यहां हर में (7) भी है, इसलिए दशमलव प्रसार सांत नहीं होगा, पर परिमेय संख्या होने के कारण वह आवर्ती होगा। चरण 3: परीक्षा में पहले भिन्न को सरलतम रूप में जांचें, फिर हर के अभाज्य गुणनखंड देखें।
