Answer 1

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