1.	\(\sqrt{2{\frac{1}{4}}}=\,?\)A. \(2\frac{1}{2}\)B. \(1\frac{1}{2}\)C. \(1\frac{1}{4}\)D. None of these
Answer» We can solve the given question as: = \(\sqrt{2{\frac{1}{4}}}\) = \(\sqrt{\frac{9}{4}}\) = \(\frac{\sqrt{9}}{\sqrt{4}}\) = \(\frac{\sqrt{3\times3}}{\sqrt{2\times2}}\) = \(\frac{3}{2}\) = \(1\frac{1}{2}\) Hence, Option (B) is the correct option

Answer»

We can solve the given question as:

= \(\sqrt{2{\frac{1}{4}}}\)

= \(\sqrt{\frac{9}{4}}\)

= \(\frac{\sqrt{9}}{\sqrt{4}}\)

= \(\frac{\sqrt{3\times3}}{\sqrt{2\times2}}\)

= \(\frac{3}{2}\)

= \(1\frac{1}{2}\)

Hence,

Option (B) is the correct option
