Question 1/18 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 2/18 Hard Mathematics Real Numbers 7: Decimal expansion of rational numbers Class 10 Level 20

कौन-सा दशमलव \(\frac{7}{90}\) के बराबर है?

Which decimal is equal to \(\frac{7}{90}\)?

Explanation opens after your attempt
Correct Answer

B. \(0.0\overline{7}\)

Step 1

Concept

\(\frac{7}{90}=\frac{7}{9\cdot 10}\).

Step 2

Why this answer is correct

\(\frac{7}{9}=0.\overline{7}\), so dividing by (10) gives \(0.0\overline{7}\).

Step 3

Exam Tip

A factor (10) in the denominator shifts the decimal one place. चरण 1: \(\frac{7}{90}=\frac{7}{9\cdot 10}\) है। चरण 2: \(\frac{7}{9}=0.\overline{7}\), इसलिए (10) से भाग देने पर \(0.0\overline{7}\) मिलता है। चरण 3: हर में (10) होने से दशमलव एक स्थान आगे खिसकता है।

Question 3/18 Medium Mathematics Real Numbers 7: Decimal expansion of rational numbers Class 10 Level 19

किस दशमलव का सरल भिन्न रूप \(\frac{7}{20}\) है?

Which decimal has \(\frac{7}{20}\) as its simplest fraction form?

Explanation opens after your attempt
Correct Answer

A. (0.35)

Step 1

Concept

Multiply denominator (20) by (5) to make (100).

Step 2

Why this answer is correct

\(\frac{7}{20}=\frac{35}{100}=0.35\).

Step 3

Exam Tip

Exam tip: With denominator (20), make (100) for a quick answer. चरण 1: \(\frac{7}{20}\) में हर (20) को (100) बनाने के लिए (5) से गुणा करें। चरण 2: \(\frac{7}{20}=\frac{35}{100}=0.35\) है। चरण 3: परीक्षा सुझाव: हर (20) हो तो (100) बनाकर उत्तर जल्दी मिलता है।

Question 4/18 Medium Mathematics Real Numbers 7: Decimal expansion of rational numbers Class 10 Level 19

कौन सा विकल्प \(\frac{7}{80}\) के सही दशमलव प्रसार को दिखाता है?

Which option shows the correct decimal expansion of \(\frac{7}{80}\)?

Explanation opens after your attempt
Correct Answer

A. (0.0875)

Step 1

Concept

\(80\times125=10000\).

Step 2

Why this answer is correct

\(\frac{7}{80}=\frac{875}{10000}=0.0875\).

Step 3

Exam Tip

Exam tip: Missing the zero after the decimal point changes the answer. चरण 1: \(80\times125=10000\) है। चरण 2: \(\frac{7}{80}=\frac{875}{10000}=0.0875\) है। चरण 3: परीक्षा सुझाव: दशमलव से पहले आने वाले शून्य को छोड़ना उत्तर बदल देता है।

Question 5/18 Medium Mathematics Real Numbers 7: Decimal expansion of rational numbers Class 10 Level 19

कौन सा विकल्प \(\frac{3}{32}\) के सही दशमलव रूप को दिखाता है?

Which option shows the correct decimal form of \(\frac{3}{32}\)?

Explanation opens after your attempt
Correct Answer

A. (0.09375)

Step 1

Concept

\(32=2^5\), so the decimal ends after (5) places.

Step 2

Why this answer is correct

\(32\times3125=100000\), so \(\frac{3}{32}=\frac{9375}{100000}=0.09375\).

Step 3

Exam Tip

Exam tip: Count the total decimal places carefully while placing the decimal point. चरण 1: \(32=2^5\) है, इसलिए दशमलव (5) स्थानों पर समाप्त होगा। चरण 2: \(32\times3125=100000\), अतः \(\frac{3}{32}=\frac{9375}{100000}=0.09375\)। चरण 3: परीक्षा सुझाव: दशमलव बिंदु लगाते समय कुल स्थानों की गिनती करें।

Question 15/18 Easy Mathematics Real Numbers 7: Decimal expansion of rational numbers Class 10 Level 20

किस भिन्न का दशमलव विस्तार ठीक तीन दशमलव स्थानों तक जाएगा?

Which fraction has a decimal expansion that goes exactly up to three decimal places?

Explanation opens after your attempt
Correct Answer

A. \(\frac{7}{200}\)

Step 1

Concept

\(200=2^3\times5^2\).
