Hard Mathematics Real Numbers Class 10 Level 21

यदि \(0.00\overline{45}\) को सरलतम भिन्न \(\frac{p}{q}\) में लिखा जाए, तो (q) क्या होगा?

If \(0.00\overline{45}\) is written as \(\frac{p}{q}\) in lowest form, what is (q)?

Explanation opens after your attempt
Correct Answer

D. (2200)

Step 1

Concept

\(0.00\overline{45}=0.00454545\ldots\).

Step 2

Why this answer is correct

It equals \(\frac{45}{9900}=\frac{1}{220}\). So the denominator is (220).

Step 3

Exam Tip

Choose the denominator only after reducing. चरण 1: \(0.00\overline{45}=0.00454545\ldots\) है। चरण 2: यह \(\frac{45}{9900}=\frac{1}{220}\) होता है। इसलिए हर (220) है। चरण 3: सरल करने के बाद ही हर चुनें।
