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)=$( \frac{32}{5} * \frac{35}{12} -16)*2* \frac{1}{4}=( \frac{56}{3} -16)*2= \frac{2}{3} *2=1 \frac{1}{3}$
