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

कौन-सा दशमलव परिमेय है लेकिन सांत दशमलव के बराबर नहीं है?

Which decimal is rational but not equal to a terminating decimal?

Explanation opens after your attempt
Correct Answer

B. \(0.04\overline{6}\)

Step 1

Concept

\(0.04\overline{6}\) has a fixed repeating digit, so it is rational but not terminating. A decimal is terminating only when zeros continue after some point.

Step 2

Why this answer is correct

The correct answer is B. \(0.04\overline{6}\). \(0.04\overline{6}\) has a fixed repeating digit, so it is rational but not terminating. A decimal is terminating only when zeros continue after some point.

Step 3

Exam Tip

\(0.04\overline{6}\) में स्थिर आवर्ती अंक है इसलिए यह परिमेय है पर सांत नहीं है। अंत में केवल शून्य आने पर ही सांत दशमलव माना जाता है।

Question 2/2 Expert Mathematics Real Numbers 7: Decimal expansion of rational numbers Class 10 Level 19

किस दशमलव को देखकर निश्चित रूप से परिमेय संख्या कहा जा सकता है?

Which decimal can definitely be called a rational number?

Explanation opens after your attempt
Correct Answer

C. \(0.58\overline{23}\)

Step 1

Concept

In \(0.58\overline{23}\), the block (23) repeats regularly, so it is rational. A fixed repeating block is a strong sign of rationality.

Step 2

Why this answer is correct

The correct answer is C. \(0.58\overline{23}\). In \(0.58\overline{23}\), the block (23) repeats regularly, so it is rational. A fixed repeating block is a strong sign of rationality.

Step 3

Exam Tip

\(0.58\overline{23}\) में (23) स्थिर रूप से दोहरता है, इसलिए यह परिमेय है। स्थिर आवर्ती खंड परिमेयता का मजबूत संकेत है।
