What is the decimal form of \( \frac{7}{40} \)?
A. (0.175)
\( \frac{7}{40}=\frac{175}{1000}=0.175 \) है। हर को (1000) बनाने से दशमलव जल्दी मिलता है। / \( \frac{7}{40}=\frac{175}{1000}=0.175 \). Making the denominator (1000) gives the decimal quickly.

Which is the decimal form of \( \frac{19}{80} \)?
B. (0.2375)
\(80\times125=10000\), इसलिए \( \frac{19}{80}=\frac{2375}{10000}=0.2375 \) है। हर को (10) की घात बनाएं। / \(80\times125=10000\), so \( \frac{19}{80}=\frac{2375}{10000}=0.2375 \). Make the denominator a power of (10).

In simplest form, what type of decimal expansion will \( \frac{13}{150} \) have?
D. असांत आवर्तीNon-terminating recurring
\(150=2\times3\times5^2\) में (3) भी है। परिमेय संख्या होने से यह असांत आवर्ती दशमलव देगी। / \(150=2\times3\times5^2\) also has (3). Since it is rational, it will give a non-terminating recurring decimal.

Which is the expanded form of (2.045)?
A. \(2+\frac{4}{100}+\frac{5}{1000}\)
(4) सौवें और (5) हजारवें स्थान पर है। इसलिए \(2.045=2+\frac{4}{100}+\frac{5}{1000}\) है। / (4) is in the hundredths place and (5) is in the thousandths place. So \(2.045=2+\frac{4}{100}+\frac{5}{1000}\).

Which number lies between (0.56) and (0.57)?
C. (0.565)
(0.565), (0.560) से बड़ा और (0.570) से छोटा है। तुलना में दशमलव स्थान समान करें। / (0.565) is greater than (0.560) and less than (0.570). Make decimal places equal while comparing.

In simplest form, what type of decimal expansion will \( \frac{21}{125} \) have?
C. सांतTerminating
\(125=5^3\) है, इसलिए हर में केवल (5) है। ऐसे हर वाली भिन्न सांत दशमलव देती है। / \(125=5^3\), so the denominator has only (5). A fraction with such a denominator gives a terminating decimal.
