ПОМОГИТЕ СРОЧНО

Answer 1

$4 frac{1}{7} + frac{2}{3} + 1 frac{11}{21} = 4 frac{3}{21} + frac{14}{21} + 1 frac{11}{21} = 5 frac{28}{21} = 6 frac{7}{21} = 6 frac{1}{3}$
$2 frac{1}{2} + 3 frac{2}{3} + 4 frac{3}{4} = 2 frac{6}{12} + 3 frac{8}{12} + 4 frac{9}{12} = 9 frac{23}{12} = 10 frac{11}{12}$
$1 frac{1}{3} + frac{7}{30} + 2 frac{3}{5} = 1 frac{10}{30} + frac{7}{30} + 2 frac{18}{30} = 3 frac{35}{30} = 4 frac{5}{30} = 4 frac{1}{6}$
