Answer 1

$( \sqrt{ \frac{3}{10} \div \frac{8}{15} } ) + ( \frac{3}{4} + \frac{1}{2} ) \times \frac{2}{3} = \\ = ( \sqrt{ \frac{3}{10} \times \frac{15}{8} } ) + ( \frac{3}{4} + \frac{2}{4} ) \times \frac{2}{3} = \\ = ( \sqrt{ \frac{45}{80} } ) + ( \frac{5}{4} ) \frac{2}{3} = \\ = \sqrt{ \frac{9}{16} } + \frac{5}{4} \times \frac{2}{3} = \\ = \frac{3}{4} + \frac{10}{12} = \frac{9}{12} + \frac{10}{12} =\boxed{ \frac{19}{12}}$
