Correct Answer

B. असमाप्त आवर्तीNon-terminating recurring

For a terminating decimal, the denominator should have only (2) and (5).

If (3) remains, the decimal will not terminate and will be recurring because the number is rational.

Step 3

Exam Tip

The remaining factors in lowest form decide the result. चरण 1: समाप्त दशमलव के लिए भाजक में केवल (2) और (5) होने चाहिए। चरण 2: (3) बचने पर दशमलव समाप्त नहीं होगा और परिमेय होने से आवर्ती होगा। चरण 3: सरल रूप में बचे गुणनखंड ही निर्णय करते हैं।
