$\frac{ \frac{1}{2} - \frac{1}{7} - \frac{1}{4} }{2 \frac{5}{14}-1 \frac{8}{21} - \frac{1}{3} } + \frac{5.3*0.7+1.29}{7.3-1.04:0.8} =1 \frac{1}{48}\\1) \frac{ \frac{1}{2} - \frac{1}{7} - \frac{1}{4} }{2 \frac{5}{14}-1 \frac{8}{21} - \frac{1}{3} } = \frac{ \frac{14-4-7}{28} }{ \frac{32}{14}- \frac{29}{21} - \frac{1}{3} } = \frac{ \frac{3}{28} }{ \frac{96}{42} - \frac{58}{42}- \frac{14}{42} } = \frac{ \frac{3}{28} }{ \frac{24}{42} } = \frac{3*42}{28*24} = \frac{3}{16}$
$2) \frac{5.3*0.7+1.29}{7.3-1.04:0.8} = \frac{5}{6} \\3) \frac{3}{16} + \frac{5}{6} = \frac{9}{48} + \frac{40}{48} =1 \frac{1}{48}$
