Номер 105 помогите плиз

Answer 1

1)$= frac{29}{7} + frac{17}{14} *( frac{43}{5} - frac{8}{5} )= frac{29}{7} + frac{17}{14}*7=12 frac{9}{14}$
2)=$2 frac{5}{9} *2 frac{1}{4} -6 frac{2}{9} * frac{3}{8} = frac{23}{9} * frac{9}{4} - frac{56}{9} * frac{3}{8} =23* frac{1}{4} - frac{7}{3} = frac{41}{12} =3 frac{5}{12}$
3)=$( frac{32}{5} * frac{35}{12} -16)*2* frac{1}{4}=( frac{56}{3} -16)*2= frac{2}{3} *2=1 frac{1}{3}$
