[tex] \frac{ \sqrt{7} }{ \sqrt{2} } = \frac{ \sqrt{7} \sqrt{2} }{ \sqrt{2} \sqrt{2} } = \frac{ \sqrt{14} }{2} [/tex]
[tex] \frac{ \sqrt{5} }{ \sqrt{12} } = \frac{ \sqrt{5} }{2 \sqrt{3} } = \frac{ \sqrt{5} \sqrt{3} }{2 \sqrt{3} \sqrt{3} } = \frac{ \sqrt{15} }{6} [/tex]
[tex] \frac{ \sqrt{8} }{ \sqrt{36} } = \frac{2 \sqrt{2} }{6} = \frac{ \sqrt{2} }{3} [/tex]
