[tex] \frac{2}{3} + \frac{1}{4} = \frac{8 + 3}{12} = \frac{11}{12} \\ \\ 5 \frac{3}{2}- 2 \frac{1}{3} = \frac{13}{2} - \frac{7}{3} = \frac{39 - 14}{6} = \frac{25}{6} = 4\frac{1}{6} \\ \\ \frac{5}{9} \times \frac{18}{15} = \frac{90}{135} = \frac{10}{15} \\ \\ \frac{7}{20} \div \frac{21}{5} = \frac{35}{420} \\ \\ ( \frac{2}{3} )^{2} = \frac{2}{3} \times \frac{2}{3} = \frac{4}{9} \\ \\ \sqrt{ \frac{4}{36} } = \frac{ \sqrt{4} }{ \sqrt{36} } = \frac{2}{6} = \frac{1}{3} [/tex]
