Question 1/12 Expert Mathematics Chapter 1: Real Numbers 7: Decimal expansion of rational numbers Class 10 Level 21

\(\frac{22}{2^2\cdot 5^4\cdot 11^2}\) का दशमलव प्रसार कैसा होगा?

What type of decimal expansion will \(\frac{22}{2^2\cdot 5^4\cdot 11^2}\) have?

Explanation opens after your attempt
Correct Answer

B. असांत आवर्तीNon-terminating recurring

Step 1

Concept

After cancelling \(22=2\cdot 11\), the denominator becomes \(2\cdot 5^4\cdot 11\). Since (11) remains, the decimal is non-terminating recurring.

Step 2

Why this answer is correct

The correct answer is B. असांत आवर्ती / Non-terminating recurring. After cancelling \(22=2\cdot 11\), the denominator becomes \(2\cdot 5^4\cdot 11\). Since (11) remains, the decimal is non-terminating recurring.

Step 3

Exam Tip

\(22=2\cdot 11\) कटने पर हर \(2\cdot 5^4\cdot 11\) बचेगा। (11) बचने से दशमलव असांत आवर्ती होगा।

Question 4/12 Expert Mathematics Chapter 1: Real Numbers 7: Decimal expansion of rational numbers Class 10 Level 19

\(\frac{125}{2^8\cdot 5^6\cdot 11}\) का दशमलव प्रसार कैसा होगा?

What type of decimal expansion will \(\frac{125}{2^8\cdot 5^6\cdot 11}\) have?

Explanation opens after your attempt
Correct Answer

B. असांत आवर्तीNon-terminating recurring

Step 1

Concept

Even after \(125=5^3\) cancels, (11) remains in the denominator. If a reduced denominator has a prime other than (2) and (5), the decimal is non-terminating recurring.

Step 2

Why this answer is correct

The correct answer is B. असांत आवर्ती / Non-terminating recurring. Even after \(125=5^3\) cancels, (11) remains in the denominator. If a reduced denominator has a prime other than (2) and (5), the decimal is non-terminating recurring.

Step 3

Exam Tip

\(125=5^3\) कटने पर भी हर में (11) बचता है। सरलतम हर में (2) और (5) के अलावा कोई अभाज्य रहे तो दशमलव असांत आवर्ती होता है।

Question 5/12 Hard Mathematics Chapter 1: Real Numbers 7: Decimal expansion of rational numbers Class 10 Level 21

कौन-सी भिन्न का दशमलव प्रसार सांत नहीं होगा?

Which fraction will not have a terminating decimal expansion?

Explanation opens after your attempt
Correct Answer

C. \(\frac{50}{2\cdot 5^2\cdot 7}\)

Step 1

Concept

Look for any factor other than (2) and (5) that remains in the denominator.

Step 2

Why this answer is correct

In \(\frac{50}{2\cdot 5^2\cdot 7}\), \(50=2\cdot 5^2\) cancels, but (7) remains. So the decimal is non-terminating recurring.

Step 3

Exam Tip

The remaining prime factors after cancellation decide the type. चरण 1: हर में (2) और (5) के अलावा बचने वाले गुणनखंड को देखें। चरण 2: \(\frac{50}{2\cdot 5^2\cdot 7}\) में \(50=2\cdot 5^2\) कटता है, लेकिन (7) हर में बचता है। इसलिए दशमलव असांत आवर्ती होगा। चरण 3: पूरी कटौती के बाद बचे अभाज्य गुणनखंड निर्णायक होते हैं।

Question 6/12 Hard Mathematics Chapter 1: Real Numbers 7: Decimal expansion of rational numbers Class 10 Level 19

\(\frac{27}{990}\) का दशमलव प्रसार कैसा है?

What type of decimal expansion does \(\frac{27}{990}\) have?

Explanation opens after your attempt
Correct Answer

B. असांत आवर्तीNon-terminating recurring

Step 1

Concept

\(\frac{27}{990}=\frac{3}{110}\).

Step 2

Why this answer is correct

\(110=2\cdot 5\cdot 11\), so (11) remains in the denominator. Hence the decimal is non-terminating recurring.

Step 3

Exam Tip

If a reduced denominator has a prime other than (2) or (5), it will not terminate. चरण 1: \(\frac{27}{990}=\frac{3}{110}\) है। चरण 2: \(110=2\cdot 5\cdot 11\), जिसमें (11) बचता है। इसलिए दशमलव असांत आवर्ती होगा। चरण 3: सरलतम हर में (2) और (5) के अलावा कोई गुणनखंड रहे तो सांत नहीं होगा।

Question 7/12 Hard Mathematics Chapter 1: Real Numbers 7: Decimal expansion of rational numbers Class 10 Level 19

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।

Question 8/12 Medium Mathematics Chapter 1: Real Numbers 7: Decimal expansion of rational numbers Class 10 Level 20

\(\frac{9}{28}\) का दशमलव प्रसार समाप्त क्यों नहीं होगा?

Why will the decimal expansion of \(\frac{9}{28}\) not terminate?

Explanation opens after your attempt
Correct Answer

A. क्योंकि हर में (7) भी हैBecause the denominator also contains (7)

Step 1

Concept

\(28=2^2\times7\).

Step 2

Why this answer is correct

The reduced denominator contains (7), which is not (2) or (5).

Step 3

Exam Tip

If another prime factor remains, the decimal is non-terminating recurring. चरण 1: \(28=2^2\times7\) है। चरण 2: सरलतम हर में (7) है, जो (2) या (5) नहीं है। चरण 3: अन्य अभाज्य गुणनखंड रहने पर दशमलव असमाप्त आवर्ती होता है।

Question 9/12 Easy Mathematics Chapter 1: Real Numbers 7: Decimal expansion of rational numbers Class 10 Level 20

यदि \(\frac{p}{q}\) सरल रूप में है और (q=75) है, तो दशमलव विस्तार कैसा होगा?

If \(\frac{p}{q}\) is in lowest form and (q=75), what type of decimal expansion will it have?

Explanation opens after your attempt
Correct Answer

B. असमाप्त आवर्तीNon-terminating recurring

Step 1

Concept

\(75=3\times5^2\).

Step 2

Why this answer is correct

The factor (3) remains in the denominator, so the decimal will not terminate and will recur.

Step 3

Exam Tip

If the reduced denominator is not of the form \(2^m5^n\), it does not terminate. चरण 1: \(75=3\times5^2\) है। चरण 2: भाजक में (3) बचा है, इसलिए दशमलव समाप्त नहीं होगा और आवर्ती होगा। चरण 3: सरल रूप का भाजक \(2^m5^n\) न हो तो समाप्ति नहीं होती।

Question 10/12 Easy Mathematics Chapter 1: Real Numbers 7: Decimal expansion of rational numbers Class 10 Level 19

सरल रूप में भाजक (14) वाली भिन्न का दशमलव विस्तार कैसा होगा?

What type of decimal expansion will a fraction have if its denominator in lowest form is (14)?

Explanation opens after your attempt
Correct Answer

B. असमाप्त आवर्तीNon-terminating recurring

Step 1

Concept

\(14=2\times7\).

Step 2

Why this answer is correct

The factor (7) prevents termination, and because the number is rational, the decimal is recurring.

Step 3

Exam Tip

Even one extra prime factor stops termination. चरण 1: \(14=2\times7\) है। चरण 2: भाजक में (7) होने से दशमलव समाप्त नहीं होगा और परिमेय होने से आवर्ती होगा। चरण 3: केवल एक अतिरिक्त गुणनखंड भी समाप्ति रोक देता है।

Question 11/12 Easy Mathematics Chapter 1: Real Numbers 7: Decimal expansion of rational numbers Class 10 Level 19

\(\frac{77}{210}\) को सरल करने के बाद उसका दशमलव विस्तार कैसा होगा?

After reducing \(\frac{77}{210}\), what type of decimal expansion will it have?

Explanation opens after your attempt
Correct Answer

B. असमाप्त आवर्तीNon-terminating recurring

Step 1

Concept

\(\frac{77}{210}=\frac{11}{30}\).

Step 2

Why this answer is correct

Since \(30=2\times3\times5\), the factor (3) remains, so the decimal is recurring.

Step 3

Exam Tip

Always check the denominator after reducing. चरण 1: \(\frac{77}{210}=\frac{11}{30}\) है। चरण 2: \(30=2\times3\times5\), इसलिए भाजक में (3) बचता है और दशमलव आवर्ती होगा। चरण 3: केवल मूल भाजक नहीं, सरल रूप का भाजक देखें।

Question 12/12 Easy Mathematics Chapter 1: Real Numbers 7: Decimal expansion of rational numbers Class 10 Level 19

\(\frac{11}{45}\) के दशमलव विस्तार के बारे में सही कथन चुनिए।

Choose the correct statement about the decimal expansion of \(\frac{11}{45}\).

Explanation opens after your attempt
Correct Answer

B. यह असमाप्त आवर्ती होगाIt will be non-terminating recurring

Step 1

Concept

\(45=3^2\times5\).

Step 2

Why this answer is correct

The factor (3) stops termination, but the number is rational, so the decimal repeats.

Step 3

Exam Tip

A non-terminating decimal of a rational number is recurring. चरण 1: \(45=3^2\times5\) है। चरण 2: भाजक में (3) होने से दशमलव समाप्त नहीं होगा, लेकिन परिमेय संख्या होने के कारण आवर्ती होगा। चरण 3: परिमेय संख्या का असमाप्त दशमलव हमेशा आवर्ती होता है।
