What is obtained when (0.00096) is converted into a simplified fraction?
C. \( \frac{3}{3125} \)
\(0.00096=\frac{96}{100000}=\frac{3}{3125}\) है। पांच दशमलव स्थान होने पर हर (100000) लें। / \(0.00096=\frac{96}{100000}=\frac{3}{3125}\). For five decimal places, take denominator (100000).

What is the decimal form of \( \frac{7}{64} \)?
A. (0.109375)
\(64\times15625=1000000\), इसलिए \( \frac{7}{64}=0.109375 \) है। (2) की घात वाले हर को (10) की घात में बदला जा सकता है। / \(64\times15625=1000000\), so \( \frac{7}{64}=0.109375 \). A denominator that is a power of (2) can be converted to a power of (10).

If the decimal expansion of \( \frac{18}{45} \) is found, which conclusion is correct?
C. सांत क्योंकि सरल रूप \( \frac{2}{5} \) हैTerminating because the simplest form is \( \frac{2}{5} \)
\( \frac{18}{45}=\frac{2}{5} \) और (5) केवल (5) का गुणनखंड है। पहले भिन्न को सरल रूप में बदलना जरूरी है। / \( \frac{18}{45}=\frac{2}{5} \), and (5) has only factor (5). It is necessary to simplify the fraction first.

Which is the expanded form of (2.5005)?
B. \(2+\frac{5}{10}+\frac{5}{10000}\)
पहला (5) दसवें और अंतिम (5) दस हजारवें स्थान पर है। शून्य वाले स्थानों का मान अलग से लिखना आवश्यक नहीं होता। / The first (5) is in tenths and the last (5) is in ten-thousandths. Zero-value places need not be written separately.

What is the value of \(0.125\div0.0005\)?
B. (250)
दोनों को (10000) से गुणा करने पर \(1250\div5=250\) मिलता है। दशमलव भाग में समान गुणा करने से भागफल नहीं बदलता। / Multiplying both by (10000) gives \(1250\div5=250\). Multiplying both parts of a division by the same number does not change the quotient.

What is the value of (3.075-0.6085)?
A. (2.4665)
(3.075=3.0750), इसलिए (3.0750-0.6085=2.4665) है। घटाते समय दशमलव स्थान समान करें। / (3.075=3.0750), so (3.0750-0.6085=2.4665). Make decimal places equal while subtracting.

What is the value of (0.0375+0.00625+0.000875)?
A. (0.044625)
समान दशमलव स्थान लिखने पर (0.037500+0.006250+0.000875=0.044625) मिलता है। जोड़ते समय दशमलव बिंदु सीध में रखें। / Writing equal decimal places gives (0.037500+0.006250+0.000875=0.044625). Align decimal points while adding.

Which statement about \(0.999\ldots\) and (1) is correct?
C. \(0.999\ldots=1\)
\(0.999\ldots=1\) एक मानक आवर्ती दशमलव परिणाम है। परीक्षा में \(0.\overline{9}\) को (1) के बराबर मानें। / \(0.999\ldots=1\) is a standard recurring decimal result. In exams, treat \(0.\overline{9}\) as equal to (1).

Which decimal is greater than \( \frac{11}{20} \) and less than \( \frac{5}{9} \)?
C. (0.554)
\( \frac{11}{20}=0.55 \) और \( \frac{5}{9}=0.555\ldots \), इसलिए (0.554) इनके बीच है। सीमाओं को दशमलव में बदलें। / \( \frac{11}{20}=0.55 \) and \( \frac{5}{9}=0.555\ldots \), so (0.554) lies between them. Convert the boundaries into decimals.

If (0.68b<0.684), how many values of digit (b) are possible?
B. (4)
हजारवें स्थान पर (b<4) होना चाहिए। इसलिए (b=0,1,2,3) यानी (4) मान संभव हैं। / At the thousandths place, (b<4) is needed. So (b=0,1,2,3), giving (4) possible values.
