Answer 1

$25 frac{5}{6} + (11 frac{1}{6} - 9 frac{5}{6} ) = 25 frac{5}{6} + 1 frac{2}{6} = 27 frac{1}{6} \ \ (25 frac{11}{19} + 9 frac{8}{19} ) - 20 frac{8}{19} = 35 - 20 frac{8}{19} = 34 frac{19}{19} - 20 frac{8}{19} = 14 frac{11}{19} \ \ 28 frac{7}{20} - (9 frac{11}{20} + 5 frac{7}{20} ) = 28 frac{7}{20} - 14 frac{18}{20} = 13 frac{9}{20} \ 49 frac{19}{40} + (25 frac{21}{40} + 6 frac{13}{40} ) = 49 frac{19}{40} + 31 frac{34}{40} = 80 frac{53}{40} = 81 frac{13}{40}$
