Hard Mathematics Real Numbers Class 10 Level 20

\(0.4\overline{7}\) को सरलतम भिन्न \(\frac{p}{q}\) में लिखने पर (q) क्या होगा?

When \(0.4\overline{7}\) is written as a fraction \(\frac{p}{q}\) in lowest form, what is (q)?

Explanation opens after your attempt
Correct Answer

B. (90)

Step 1

Concept

Let \(x=0.4777\ldots\).

Step 2

Why this answer is correct

\(10x=4.777\ldots\) and \(100x=47.777\ldots\), so (90x=43) and \(x=\frac{43}{90}\).

Step 3

Exam Tip

Separate the non-repeating and repeating parts before multiplying. चरण 1: मान लें \(x=0.4777\ldots\)। चरण 2: \(10x=4.777\ldots\) और \(100x=47.777\ldots\), इसलिए (90x=43) और \(x=\frac{43}{90}\)। चरण 3: सांत भाग और आवर्ती भाग को अलग करके गुणा करें।
