Answer 3

$20 - 17 - 19 frac{2}{4} + 17 frac{3}{4} + 2 frac{1}{2} - frac{17}{24} = \ 3 - 1 frac{3}{4} + 2 frac{1}{2} - frac{17}{24} = \ 3 + frac{10 - 7}{4} - frac{17}{24} = \ 3 + frac{18 - 17}{24} = 3 frac{1}{24}$
$25 - 8 - 13 - 2 + 2 - 1 + frac{7}{9} - frac{3}{4} - frac{5}{12} - frac{11}{18} + frac{1}{6} - frac{5}{9} = \ 3 + frac{28 - 27 - 15 - 22 + 6 - 20}{36} = \ 3 - 1frac{7}{18} = 1 frac{11}{18}$
