\(0.\overline{36}\) को सरलतम रूप में लिखने पर हर क्या होगा?

What is the denominator when \(0.\overline{36}\) is written in lowest form?

Explanation opens after your attempt
Correct Answer

B. (11)

Step 1

Concept

\(0.\overline{36}=\frac{36}{99}\).

Step 2

Why this answer is correct

\(\frac{36}{99}=\frac{4}{11}\), so the reduced denominator is (11).

Step 3

Exam Tip

For a purely recurring decimal, first use a denominator of (9)'s and then reduce. चरण 1: \(0.\overline{36}=\frac{36}{99}\) है। चरण 2: \(\frac{36}{99}=\frac{4}{11}\), इसलिए सरलतम हर (11) है। चरण 3: पूर्ण आवर्ती दशमलव में पहले (9) वाला हर बनाइए, फिर सरल कीजिए।

(0.00064) को सरलतम भिन्न में लिखने पर हर क्या होगा?

What is the denominator when (0.00064) is written as a fraction in lowest form?

Explanation opens after your attempt
Correct Answer

A. (15625)

Step 1

Concept

\(0.00064=\frac{64}{100000}\).

Step 2

Why this answer is correct

Reducing by the greatest common factor (32) gives \(\frac{2}{3125}\). So the denominator is (3125).

Step 3

Exam Tip

Reduce carefully; repeated division by (2) is safe here. चरण 1: \(0.00064=\frac{64}{100000}\) है। चरण 2: \(100000=10^5=2^5\cdot 5^5\) और \(64=2^6\), इसलिए सरल करने पर \(\frac{2}{3125}\) नहीं बल्कि \(\frac{1}{1562.5}\) नहीं बन सकता। सही रूप \(\frac{64}{100000}=\frac{8}{12500}=\frac{4}{6250}=\frac{2}{3125}\) है। अतः हर (3125) है। चरण 3: बार-बार (2) से भाग देकर सुरक्षित सरलता करें।

यदि किसी सरलतम भिन्न का हर \(2^4\cdot 5^2\) है, तो दशमलव प्रसार में कितने स्थान होंगे?

If the denominator of a reduced fraction is \(2^4\cdot 5^2\), how many decimal places will its decimal expansion have?

Explanation opens after your attempt
Correct Answer

B. (4)

Step 1

Concept

The denominator has power (4) of (2) and power (2) of (5).

Step 2

Why this answer is correct

Decimal places in a terminating decimal equal the larger exponent, which is (4).

Step 3

Exam Tip

If the denominator is already reduced, do not assume further cancellation. चरण 1: हर में (2) की घात (4) और (5) की घात (2) है। चरण 2: सांत दशमलव के स्थान बड़ी घात के बराबर होते हैं, यानी (4)। चरण 3: सरलतम हर होने पर अंश से कोई और कटौती नहीं माननी चाहिए।

Step 3

Exam Tip

Do not decide the final denominator only from the number of decimal digits. चरण 1: \(0.3125=\frac{3125}{10000}\) है। चरण 2: सरल करने पर \(\frac{5}{16}\) मिलता है। इसलिए हर (16) है। चरण 3: दशमलव के अंकों की संख्या देखकर अंतिम हर तय न करें।

(0.000125) को सरलतम भिन्न में लिखने पर हर क्या होगा?

What is the denominator when (0.000125) is written as a fraction in lowest form?

Explanation opens after your attempt
Correct Answer

C. (8000)

Step 1

Concept

\(0.000125=\frac{125}{1000000}\).

Step 2

Why this answer is correct

Dividing both by (125) gives \(\frac{1}{8000}\). So the denominator is (8000).

Step 3

Exam Tip

Even when a decimal has many zeros, reduce the fraction fully. चरण 1: \(0.000125=\frac{125}{1000000}\) है। चरण 2: दोनों को (125) से भाग देने पर \(\frac{1}{8000}\) मिलता है। इसलिए हर (8000) है। चरण 3: छोटे दशमलवों में शून्य अधिक हों तो भी भिन्न को सरल करना जरूरी है।

(0.375) को सरलतम भिन्न में लिखने पर हर क्या होगा?

What is the denominator when (0.375) is written as a fraction in lowest form?

Explanation opens after your attempt
Correct Answer

A. (8)

Step 1

Concept

\(0.375=\frac{375}{1000}\).

Step 2

Why this answer is correct

Dividing numerator and denominator by (125) gives \(\frac{3}{8}\). So the denominator is (8).

Step 3

Exam Tip

Always reduce after converting a decimal to a fraction. चरण 1: \(0.375=\frac{375}{1000}\) है। चरण 2: (375) और (1000) को (125) से भाग देने पर \(\frac{3}{8}\) मिलता है। इसलिए हर (8) है। चरण 3: दशमलव को भिन्न में बदलने के बाद हमेशा सरल करें।
