यदि ग्राफ में प्रतिच्छेद बिंदु (\left\(3.75,-2.5\right\)) पढ़ा गया है, तो भिन्न रूप क्या होगा?

If the intersection point is read as (\left\(3.75,-2.5\right\)) on a graph, what is its fraction form?

Explanation opens after your attempt
Correct Answer

A. (\left\(\frac{15}{4},-\frac{5}{2}\right\))

Step 1

Concept

\(3.75=\frac{15}{4}\) and \(-2.5=-\frac{5}{2}\). It is better to convert decimal coordinates into simplified fractions.

Step 2

Why this answer is correct

The correct answer is A. (\left\(\frac{15}{4},-\frac{5}{2}\right\)). \(3.75=\frac{15}{4}\) and \(-2.5=-\frac{5}{2}\). It is better to convert decimal coordinates into simplified fractions.

Step 3

Exam Tip

\(3.75=\frac{15}{4}\) और \(-2.5=-\frac{5}{2}\)। दशमलव निर्देशांक को सरल भिन्न में बदलना बेहतर रहता है।

\(0.4\overline{7}\) को सरलतम भिन्न \(\frac{p}{q}\) में लिखने पर (q) क्या होगा?

When \(0.4\overline{7}\) is written as a fraction \(\frac{p}{q}\) in lowest form, what is (q)?

Explanation opens after your attempt
Correct Answer

B. (90)

Step 1

Concept

Let \(x=0.4777\ldots\).

Step 2

Why this answer is correct

\(10x=4.777\ldots\) and \(100x=47.777\ldots\), so (90x=43) and \(x=\frac{43}{90}\).

Step 3

Exam Tip

Separate the non-repeating and repeating parts before multiplying. चरण 1: मान लें \(x=0.4777\ldots\)। चरण 2: \(10x=4.777\ldots\) और \(100x=47.777\ldots\), इसलिए (90x=43) और \(x=\frac{43}{90}\)। चरण 3: सांत भाग और आवर्ती भाग को अलग करके गुणा करें।

\(0.\overline{45}\) का सरलतम भिन्न रूप कौन-सा है?

Which is the simplest fractional form of \(0.\overline{45}\)?

Explanation opens after your attempt
Correct Answer

C. \(\frac{5}{11}\)

Step 1

Concept

The repeating block is (45), so \(0.\overline{45}=\frac{45}{99}\).

Step 2

Why this answer is correct

\(\frac{45}{99}=\frac{5}{11}\).

Step 3

Exam Tip

Write as many (9)s in the denominator as the number of repeating digits. चरण 1: दोहराने वाला भाग (45) है, इसलिए \(0.\overline{45}=\frac{45}{99}\) है। चरण 2: \(\frac{45}{99}=\frac{5}{11}\) है। चरण 3: आवर्ती भाग के अंकों की संख्या के बराबर (9) हर में लिखें।

\(0.\overline{27}\) का सरलतम भिन्न रूप कौन-सा है?

Which is the simplest fractional form of \(0.\overline{27}\)?

Explanation opens after your attempt
Correct Answer

C. \(\frac{3}{11}\)

Step 1

Concept

The repeating block is (27), so \(0.\overline{27}=\frac{27}{99}\).

Step 2

Why this answer is correct

\(\frac{27}{99}=\frac{3}{11}\).

Step 3

Exam Tip

For recurring decimals, the number of (9)s matches the repeating digits. चरण 1: दो अंकों का आवर्ती भाग (27) है, इसलिए \(0.\overline{27}=\frac{27}{99}\) होगा। चरण 2: \(\frac{27}{99}=\frac{3}{11}\) है। चरण 3: आवर्ती दशमलव में दोहरते अंकों के लिए उतने ही (9) हर में आते हैं।

कौन सा भिन्न रूप \(0.0\overline{6}\) के बराबर है?

Which fraction is equal to \(0.0\overline{6}\)?

Explanation opens after your attempt
Correct Answer

A. \(\frac{1}{15}\)

Step 1

Concept

\(0.0\overline{6}=0.0666\ldots\).

Step 2

Why this answer is correct

It equals \(\frac{1}{15}\) because \(\frac{1}{15}=0.0666\ldots\).

Step 3

Exam Tip

Exam tip: Separate the non-repeating part and the repeating part after the decimal point. चरण 1: \(0.0\overline{6}=0.0666\ldots\) है। चरण 2: यह \(\frac{1}{15}\) के बराबर है क्योंकि \(\frac{1}{15}=0.0666\ldots\)। चरण 3: परीक्षा सुझाव: दशमलव के बाद पहले स्थिर अंक और फिर आवर्ती अंक को अलग पहचानें।

यदि \(\sqrt{2}\) परिमेय होती, तो किस कारण से उसका रूप \(\frac{p}{q}\) अंत में अस्वीकार हो जाता?

If \(\sqrt{2}\) were rational, why would its form \(\frac{p}{q}\) finally be rejected?

Explanation opens after your attempt
Correct Answer

A. क्योंकि (p) और (q) दोनों में (2) साझा गुणनखंड आ जाता हैBecause (p) and (q) get (2) as a common factor

Step 1

Concept

\(\frac{p}{q}\) was taken in lowest form.

Step 2

Why this answer is correct

The proof shows that both (p) and (q) are divisible by (2).

Step 3

Exam Tip

So the form is no longer lowest, and the assumption fails. चरण 1: \(\frac{p}{q}\) को सरलतम रूप में लिया गया था। चरण 2: प्रमाण में (p) और (q) दोनों (2) से विभाज्य निकलते हैं। चरण 3: इसलिए वह रूप सरलतम नहीं रहता और मान्यता टूट जाती है।

यदि \(\sqrt{3}\) की सिद्धि में (p) और (q) दोनों (3) से विभाज्य मिलते हैं, तो \(\frac{p}{q}\) के बारे में कौन सा कथन सही है?

If in the proof of \(\sqrt{3}\), both (p) and (q) are found divisible by (3), which statement about \(\frac{p}{q}\) is correct?

Explanation opens after your attempt
Correct Answer

A. यह सरलतम रूप में नहीं हो सकतीIt cannot be in lowest form

Step 1

Concept

If both are divisible by (3), numerator and denominator have common factor (3).

Step 2

Why this answer is correct

Such a fraction can be reduced further by (3).

Step 3

Exam Tip

Hence it cannot be in lowest form. चरण 1: दोनों (3) से विभाज्य हैं तो अंश और हर में (3) साझा गुणनखंड है। चरण 2: ऐसी भिन्न को (3) से और सरल किया जा सकता है। चरण 3: इसलिए यह सरलतम रूप में नहीं हो सकती।
