What is the decimal form of \( \frac{37}{200} \)?
D. (0.185)
\( \frac{37}{200}=\frac{185}{1000}=0.185 \) है। हर को (1000) बनाकर दशमलव जल्दी निकाला जा सकता है। / \( \frac{37}{200}=\frac{185}{1000}=0.185 \). Converting the denominator into (1000) helps find the decimal quickly.

Which is the decimal form of \( \frac{7}{40} \)?
A. (0.175)
\( \frac{7}{40}=\frac{175}{1000}=0.175 \) है। हर (40) को (1000) बनाने के लिए (25) से गुणा करें। / \( \frac{7}{40}=\frac{175}{1000}=0.175 \). Multiply denominator (40) by (25) to make (1000).

What is obtained when (0.027) is converted into a simplified fraction?
C. \( \frac{27}{1000} \)
\(0.027=\frac{27}{1000}\) है और यह पहले से सरल रूप में है। तीन दशमलव स्थान हों तो हर (1000) लें। / \(0.027=\frac{27}{1000}\) and it is already in simplest form. For three decimal places, take denominator (1000).

Which is the expanded form of (3.209)?
A. \(3+\frac{2}{10}+\frac{9}{1000}\)
(2) दसवें और (9) हजारवें स्थान पर है। इसलिए \(3.209=3+\frac{2}{10}+\frac{9}{1000}\) है। / (2) is in tenths and (9) is in thousandths. So \(3.209=3+\frac{2}{10}+\frac{9}{1000}\).

In simplest form, what type of decimal expansion will \( \frac{14}{45} \) have?
D. असांत आवर्तीNon-terminating recurring
\(45=3^2\times5\) में (3) भी है, इसलिए दशमलव सांत नहीं होगा। परिमेय संख्या होने से यह असांत आवर्ती होगा। / \(45=3^2\times5\) has (3), so the decimal will not terminate. Since it is rational, it will be non-terminating recurring.
