Question 6/12 Medium Mathematics Real Numbers Decimal expansion of rational numbers Class 10 Level 19

कौन सा विकल्प (0.0125) के सरल भिन्न रूप को सही दिखाता है?

Which option correctly shows the simplest fraction form of (0.0125)?

Explanation opens after your attempt
Correct Answer

A. \(\frac{1}{80}\)

Step 1

Concept

\(0.0125=\frac{125}{10000}\).

Step 2

Why this answer is correct

Simplifying by (125), we get \(\frac{1}{80}\).

Step 3

Exam Tip

Exam tip: Count zeros very carefully in small decimals. चरण 1: \(0.0125=\frac{125}{10000}\) है। चरण 2: \(\frac{125}{10000}\) को (125) से सरल करने पर \(\frac{1}{80}\) मिलता है। चरण 3: परीक्षा सुझाव: छोटे दशमलव में शून्यों की गिनती बहुत सावधानी से करें।

Question 7/12 Medium Mathematics Real Numbers 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 8/12 Medium Mathematics Real Numbers 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 9/12 Easy Mathematics Real Numbers Decimal expansion of rational numbers Class 10 Level 21

\(\frac{3}{40}\) का दशमलव रूप क्या होगा?

What will be the decimal form of \(\frac{3}{40}\)?

Explanation opens after your attempt
Correct Answer

B. (0.075)

Concept

\(40\times25=1000\).

Step 2

Why this answer is correct

\(\frac{3}{40}=\frac{75}{1000}=0.075\).

Step 3

Exam Tip

Exam tip: A small numerator may lead to zeros after the decimal point. चरण 1: \(40\times25=1000\) है। चरण 2: \(\frac{3}{40}=\frac{75}{1000}=0.075\) है। चरण 3: परीक्षा सुझाव: अंश छोटा हो तो दशमलव में आगे शून्य आ सकता है।
