दिलेले आहे:

0.\(\overline{52}\) हे \(\dfrac{p}{q}\) या स्वरूपात व्यक्त करा, जिथे p आणि q पूर्णांक आहेत आणि q ≠ 0.

वापरलेले सूत्र:

समजा x = 0.\(\overline{52}\)

दशक बिंदू उजवीकडे दोन स्थानी हलविण्यासाठी दोन्ही बाजूंना 100 ने गुणा:

100x = 52.\(\overline{52}\)

मग, या नवीन समीकरणापासून मूळ समीकरण वजा करा:

गणना:

100x = 52.\(\overline{52}\)

x = 0.\(\overline{52}\)

⇒ 100x - x = 52.\(\overline{52}\) - 0.\(\overline{52}\)

⇒ 99x = 52

⇒ x = \(\dfrac{52}{99}\)

∴ बरोबर उत्तर पर्याय (2) आहे.
