Answer 1

$6 frac{3}{8} times 1 frac{1}{17} - 2 frac{3}{8} div 1 frac{1}{4} + frac{2}{5} = frac{51}{8} times frac{24}{17} - frac{19}{8} div frac{5}{4} + frac{2}{5} = 3 - frac{19}{8} times frac{4}{5} + frac{2}{5} = 3 - frac{19}{10} + frac{2}{5} = 3 - frac{19}{10} + frac{4}{10} = 3 - frac{15}{10} = 1 frac{20}{10} - 1 frac{15}{10} = 1 frac{5}{10} = 1 frac{1}{2}$
