Correct Answer

A. हर परिमेय संख्या को दो सहअभाज्य पूर्णांकों के अनुपात में लिखा जा सकता हैEvery rational number can be written as a ratio of two coprime integers

Step 1

Concept

A rational number is written as \(\frac{p}{q}\).

Step 2

Why this answer is correct

In lowest form, (p) and (q) are coprime.

Step 3

Exam Tip

This property is used to create the contradiction. चरण 1: परिमेय संख्या को \(\frac{p}{q}\) के रूप में लिखा जाता है। चरण 2: उसे सरलतम रूप में लेने पर (p) और (q) सहअभाज्य होते हैं। चरण 3: यही गुण विरोधाभास बनाने में काम आता है।
