Answer 1

$5 frac{1}{6} + 3 frac{1}{18} = frac{31}{6} + frac{55}{18} = frac{93}{18} + frac{55}{18} = frac{148}{18} = 8 frac{4}{18} = 8 frac{2}{9}; \ \ 5 frac{1}{8} + 3 frac{2}{5} = frac{41}{8} + frac{17}{5} = frac{205}{40} + frac{136}{40} = frac{341}{40} = 8 frac{21}{40} \ \ 3 frac{2}{25} + 4 frac{14}{15} = frac{77}{25} + frac{74}{15} = frac{231}{75} + frac{370}{75} = frac{641}{75} = 8 frac{41}{75}$
