What is obtained when (0.00625) is written as a simplified fraction?
A. \( \frac{1}{160} \)
\(0.00625=\frac{625}{100000}=\frac{1}{160}\) है। पांच दशमलव स्थान हों तो हर (100000) लें। / \(0.00625=\frac{625}{100000}=\frac{1}{160}\). For five decimal places, use denominator (100000).

Which decimal is not equal to (0.3040)?
C. (0.0304)
(0.0304) में अंकों का स्थान बदल गया है, इसलिए यह छोटा है। केवल अंत में शून्य जोड़ने या हटाने से मान नहीं बदलता। / In (0.0304), the place of digits has changed, so it is smaller. Only adding or removing zeros at the end does not change value.

What is obtained by converting (0.064) into a percentage?
B. (6.4%)
\(0.064\times100=6.4\), इसलिए (6.4%) मिलेगा। दशमलव को प्रतिशत में बदलने के लिए (100) से गुणा करें। / \(0.064\times100=6.4\), so it becomes (6.4%). To convert a decimal into a percentage, multiply by (100).

What is obtained by dividing (8.406) by (100)?
C. (0.08406)
\(8.406\div100=0.08406\) होता है। (100) से भाग देने पर दशमलव बिंदु दो स्थान बाईं ओर जाता है। / \(8.406\div100=0.08406\). On dividing by (100), the decimal point moves two places to the left.

What is the value of (0.375+0.0625)?
A. (0.4375)
(0.3750+0.0625=0.4375) है। जोड़ते समय दशमलव बिंदुओं को एक सीध में रखें। / (0.3750+0.0625=0.4375). Align decimal points while adding.

What is the value of (5.5-2.875)?
B. (2.625)
(5.5=5.500), इसलिए (5.500-2.875=2.625) है। घटाते समय खाली दशमलव स्थानों में शून्य लगाएं। / (5.5=5.500), so (5.500-2.875=2.625). Add zeros in empty decimal places while subtracting.

What type of decimal is \(3.14114111411114\ldots\)?
C. असांत अनावर्तीNon-terminating non-recurring
इसमें निश्चित दोहराने वाला भाग नहीं है और यह समाप्त भी नहीं होता। ऐसा दशमलव असांत अनावर्ती होता है। / It has no fixed repeating part and it does not terminate. Such a decimal is non-terminating non-recurring.

Which is the decimal expansion of \( \frac{5}{22} \)?
A. \(0.2272727\ldots\)
\(5\div22=0.2272727\ldots\) होता है। यहां (27) का समूह दोहरता है। / \(5\div22=0.2272727\ldots\). Here the block (27) repeats.

In simplest form, what type of decimal expansion will \( \frac{63}{84} \) have?
C. सांतTerminating
\( \frac{63}{84}=\frac{3}{4} \) और \(4=2^2\) है। इसलिए इसका दशमलव प्रसार सांत होगा। / \( \frac{63}{84}=\frac{3}{4} \) and \(4=2^2\). Therefore, its decimal expansion will be terminating.

In simplest form, what type of decimal expansion will \( \frac{44}{66} \) have?
B. असांत आवर्तीNon-terminating recurring
\( \frac{44}{66}=\frac{2}{3} \) है। हर में (3) होने के कारण दशमलव असांत आवर्ती होगा। / \( \frac{44}{66}=\frac{2}{3} \). Since the denominator has (3), the decimal will be non-terminating recurring.
