Hard Mathematics Chapter 1: Real Numbers Class 10 Level 19

एक भिन्न सरलतम रूप में \(\frac{p}{q}\) है और (q=72) है। उसके दशमलव प्रसार के बारे में क्या कहा जा सकता है?

A fraction in lowest form is \(\frac{p}{q}\) and (q=72). What can be said about its decimal expansion?

Correct Answer

B. असांत आवर्ती होगाIt will be non-terminating recurring

Step 1

Concept

Since \(\frac{p}{q}\) is already in lowest form, check (q) directly.

Step 2

Why this answer is correct

\(72=2^3\cdot 3^2\), which contains (3). So the decimal is non-terminating recurring.

Step 3

Exam Tip

If lowest form is stated, do not overthink the numerator. चरण 1: \(\frac{p}{q}\) सरलतम रूप में है, इसलिए (q) का गुणनखंड सीधे जाँचा जाएगा। चरण 2: \(72=2^3\cdot 3^2\), जिसमें (3) है। इसलिए दशमलव असांत आवर्ती होगा। चरण 3: सरलतम रूप दिया हो तो अंश को लेकर अलग भ्रम न रखें।
