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

यदि \(\frac{p}{q}\) सरल रूप में है और (q=75) है, तो दशमलव विस्तार कैसा होगा?

If \(\frac{p}{q}\) is in lowest form and (q=75), what type of decimal expansion will it have?

Correct Answer

B. असमाप्त आवर्तीNon-terminating recurring

Step 1

Concept

\(75=3\times5^2\).

Step 2

Why this answer is correct

The factor (3) remains in the denominator, so the decimal will not terminate and will recur.

Step 3

Exam Tip

If the reduced denominator is not of the form \(2^m5^n\), it does not terminate. चरण 1: \(75=3\times5^2\) है। चरण 2: भाजक में (3) बचा है, इसलिए दशमलव समाप्त नहीं होगा और आवर्ती होगा। चरण 3: सरल रूप का भाजक \(2^m5^n\) न हो तो समाप्ति नहीं होती।
