माना `" "x=0.25bar(62)`
चूँकि, दी गई संख्या में दशमलव के बाद दो अंकों (अर्थात 25 ) पर बार नहीं हैं।
इसलिए समी० (1 ) के दोनों पक्षों में `10^(2)=100` से गुणा करने पर
`100x=25.bar(62)=25+0.bar(62)" "` (नियम द्वारा)
`=25+(62)/(99)`
`rArr" "100x=(25xx99+62)/(99)=(2475+62)/(99)=(2537)/(99)`
इस प्रकार `" "x=(2537)/(9900)" "rArr" "0.25bar(62)=(2537)/(9900)`
