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

\(0.12\overline{45}\) को सरलतम भिन्न \(\frac{p}{q}\) में लिखने पर (q) क्या होगा?

When \(0.12\overline{45}\) is written as \(\frac{p}{q}\) in lowest form, what is (q)?

Explanation opens after your attempt
Correct Answer

C. (1100)

Step 1

Concept

\(0.124545\ldots=\frac{1245-12}{9900}=\frac{1233}{9900}=\frac{137}{1100}\). Always reduce the final fraction in mixed recurring decimals.

Step 2

Why this answer is correct

The correct answer is C. (1100). \(0.124545\ldots=\frac{1245-12}{9900}=\frac{1233}{9900}=\frac{137}{1100}\). Always reduce the final fraction in mixed recurring decimals.

Step 3

Exam Tip

\(0.124545\ldots=\frac{1245-12}{9900}=\frac{1233}{9900}=\frac{137}{1100}\) है। मिश्रित आवर्ती दशमलव में अंतिम भिन्न को अवश्य सरल करें।

\(0.4\overline{27}\) को सरलतम भिन्न \(\frac{p}{q}\) में लिखने पर (q) क्या होगा?

When \(0.4\overline{27}\) is written as \(\frac{p}{q}\) in lowest form, what is (q)?

Explanation opens after your attempt
Correct Answer

B. (110)

Step 1

Concept

\(0.4272727\ldots=\frac{423}{990}=\frac{47}{110}\), so the denominator is (110). In mixed recurring decimals, the final fraction must be reduced.

Step 2

Why this answer is correct

The correct answer is B. (110). \(0.4272727\ldots=\frac{423}{990}=\frac{47}{110}\), so the denominator is (110). In mixed recurring decimals, the final fraction must be reduced.

Step 3

Exam Tip

\(0.4272727\ldots=\frac{423}{990}=\frac{47}{110}\) है इसलिए हर (110) है। मिश्रित आवर्ती दशमलव में अंतिम भिन्न को सरल करना जरूरी है।

Question Expert Mathematics Real Numbers 7: Decimal expansion of rational numbers Class 10 Level 20

\(0.0\overline{125}\) को सरलतम भिन्न \(\frac{p}{q}\) में लिखने पर (q) क्या होगा?

When \(0.0\overline{125}\) is written as \(\frac{p}{q}\) in lowest form, what is (q)?

Explanation opens after your attempt
Correct Answer

B. (1998)

Step 1

Concept

One non-repeating zero and three repeating digits give \(\frac{125}{9990}\), which reduces to \(\frac{25}{1998}\). In mixed recurring decimals, do not treat the first denominator as the final one.

Step 2

Why this answer is correct

The correct answer is B. (1998). One non-repeating zero and three repeating digits give \(\frac{125}{9990}\), which reduces to \(\frac{25}{1998}\). In mixed recurring decimals, do not treat the first denominator as the final one.

Step 3

Exam Tip

एक अनावर्ती शून्य और तीन आवर्ती अंकों से \(\frac{125}{9990}\) बनता है, जो \(\frac{25}{1998}\) तक सरल होता है। मिश्रित आवर्ती दशमलव में पहले बना हर अंतिम हर नहीं मानें।

Question Expert Mathematics Real Numbers 7: Decimal expansion of rational numbers Class 10 Level 19

\(0.3\overline{18}\) को सरलतम भिन्न में बदलने पर हर कौन-सा है?

What is the denominator when \(0.3\overline{18}\) is converted to lowest fraction form?

Explanation opens after your attempt
Correct Answer

A. (22)

Step 1

Concept

\(0.3\overline{18}=0.3181818\ldots=\frac{315}{990}=\frac{7}{22}\). Always reduce the final fraction in mixed recurring decimals.

Step 2

Why this answer is correct

The correct answer is A. (22). \(0.3\overline{18}=0.3181818\ldots=\frac{315}{990}=\frac{7}{22}\). Always reduce the final fraction in mixed recurring decimals.

Step 3

Exam Tip

\(0.3\overline{18}=0.3181818\ldots=\frac{315}{990}=\frac{7}{22}\)। मिश्रित आवर्ती दशमलव में अंतिम उत्तर हमेशा सरल करें।

\(0.02\overline{7}\) को सरलतम भिन्न \(\frac{p}{q}\) में लिखने पर (q) क्या होगा?

When \(0.02\overline{7}\) is written as \(\frac{p}{q}\) in lowest form, what is (q)?

Explanation opens after your attempt
Correct Answer

A. (36)

Step 1

Concept

Let \(x=0.027777\ldots\).

Step 2

Why this answer is correct

\(100x=2.7777\ldots\) and \(1000x=27.7777\ldots\), so (900x=25) and \(x=\frac{25}{900}=\frac{1}{36}\).

Step 3

Exam Tip

For a mixed recurring decimal, separate the non-repeating and repeating parts before multiplying. चरण 1: मान लें \(x=0.027777\ldots\)। चरण 2: \(100x=2.7777\ldots\) और \(1000x=27.7777\ldots\), इसलिए (900x=25) और \(x=\frac{25}{900}=\frac{1}{36}\)। चरण 3: मिश्रित आवर्ती दशमलव में अनावर्ती और आवर्ती भाग को अलग करके गुणा करें।

Question Hard Mathematics Real Numbers 7: Decimal expansion of rational numbers Class 10 Level 21

कौन-सा दशमलव \(\frac{13}{99}\) के बराबर है?

Which decimal is equal to \(\frac{13}{99}\)?

Explanation opens after your attempt
Correct Answer

A. \(0.\overline{13}\)

Step 1

Concept

The purely recurring decimal \(0.\overline{13}\) equals \(\frac{13}{99}\).

Step 2

Why this answer is correct

The two (9)'s in the denominator match the two repeating digits.

Step 3

Exam Tip

Distinguish purely recurring decimals from mixed recurring decimals. चरण 1: दो अंकों वाला पूर्ण आवर्ती दशमलव \(0.\overline{13}\) \(\frac{13}{99}\) के बराबर होता है। चरण 2: हर में दो (9) आवर्ती भाग के दो अंकों को दिखाते हैं। चरण 3: पूर्ण आवर्ती और मिश्रित आवर्ती दशमलव में अंतर रखें।

Question Medium Mathematics Real Numbers 7: Decimal expansion of rational numbers Class 10 Level 21

\(0.1\overline{6}\) का भिन्न रूप कौन-सा है?

Which is the fractional form of \(0.1\overline{6}\)?

Explanation opens after your attempt
Correct Answer

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

Step 1

Concept

\(0.1\overline{6}=0.1666\ldots\).

Step 2

Why this answer is correct

This is equal to \(\frac{1}{6}\).

Step 3

Exam Tip

In a mixed recurring decimal, identify the non-repeating part and then the repeating part. चरण 1: \(0.1\overline{6}=0.1666\ldots\) है। चरण 2: यह प्रसिद्ध रूप से \(\frac{1}{6}\) के बराबर है। चरण 3: मिश्रित आवर्ती दशमलव में पहले गैर-आवर्ती भाग और फिर दोहराने वाला भाग पहचानें।

\(0.04\overline{7}\) के बारे में सही कथन कौन-सा है?

Which statement is correct about \(0.04\overline{7}\)?

Explanation opens after your attempt
Correct Answer

B. यह परिमेय संख्या है जिसका दशमलव असमाप्त आवर्ती हैIt is a rational number with a non-terminating recurring decimal

Step 1

Concept

In \(0.04\overline{7}\), the digit (7) repeats.

Step 2

Why this answer is correct

The decimal does not terminate, but it has a fixed repeating pattern.

Step 3

Exam Tip

A non-terminating decimal with a fixed repetition represents a rational number. चरण 1: \(0.04\overline{7}\) में (7) बार-बार दोहरता है। चरण 2: ऐसा दशमलव समाप्त नहीं होता, लेकिन इसमें निश्चित दोहराव है। चरण 3: निश्चित दोहराव वाला असमाप्त दशमलव परिमेय संख्या को दर्शाता है।

\(0.2\overline{3}\) को भिन्न में बदलने पर सही रूप कौन-सा है?

Which is the correct fractional form of \(0.2\overline{3}\)?

Explanation opens after your attempt
Correct Answer

A. \(\frac{7}{30}\)

Step 1

Concept

\(0.2\overline{3}=0.2333\ldots\).

Step 2

Why this answer is correct

Converting it gives \(\frac{7}{30}\).

Step 3

Exam Tip

For a mixed recurring decimal, separate the non-repeating and repeating parts carefully. चरण 1: \(0.2\overline{3}=0.2333\ldots\) है। चरण 2: इसे सरल करने पर \(\frac{7}{30}\) मिलता है। चरण 3: मिश्रित आवर्ती दशमलव में गैर-आवर्ती और आवर्ती भाग अलग-अलग पहचानें।

दशमलव \(0.2\overline{3}\) का स्वभाव कैसा है?

What is the nature of the decimal \(0.2\overline{3}\)?

Explanation opens after your attempt
Correct Answer

B. असमाप्त आवर्तीNon-terminating recurring

Step 1

Concept

In \(0.2\overline{3}\), after (2), the digit (3) repeats.

Step 2

Why this answer is correct

The decimal does not terminate and has a repeating digit, so it is recurring.

Step 3

Exam Tip

The bar is placed only over the repeating part. चरण 1: \(0.2\overline{3}\) में (2) के बाद (3) बार-बार आता है। चरण 2: यह दशमलव समाप्त नहीं होता और एक अंक दोहरता है, इसलिए आवर्ती है। चरण 3: बार केवल दोहरने वाले भाग पर लगाया जाता है।
