Answer 3

и восьми

Answer 4

$( frac{4}{5}+ frac{1}{6} )*(23 frac{2}{3}-15 frac{5}{9})* frac{45}{58} - frac{1}{2} =$$5 frac{7}{12}$

1) $frac{4}{5}+ frac{1}{6} = frac{24}{30}+ frac{5}{30}= frac{29}{30}$

2) $23 frac{2}{3}-15 frac{5}{9} =23 frac{6}{9}-15 frac{5}{9}=8 frac{1}{9}$

3) $frac{29}{30}* frac{73}{9}* frac{45}{58}= frac{73}{12}=6 frac{1}{12}$

4) $6 frac{1}{12} - frac{1}{2}= 6 frac{1}{12} - frac{6}{12}=5 frac{7}{12}$
