Verified answer

$28 \frac{2}{9} -1 \frac{8}{9} \cdot 1 \frac{1}{14} \cdot \frac{7}{17} = \frac{254}{9} -\frac{17}{9} \cdot \frac{15}{14} \cdot \frac{7}{17} = \frac{254}{9} -\frac{1}{3} \cdot \frac{5}{2} \cdot \frac{1}{1} = \frac{254}{9} - \frac{5}{6} = \\\\
= \frac{508}{18} - \frac{15}{18}= \frac{493}{18}= 27 \frac{7}{18}$
