Jawaban:

$3 frac{2}{5} + 2 frac{6}{7} = frac{17}{5} + frac{20}{7} = frac{7 times 17 + 5 times 20}{35} = frac{219}{35} = 6 frac{9}{35}$

$11 frac{4}{8} + 15 frac{5}{8} = frac{92}{8 } + frac{125}{8} = frac{92 + 125}{8} = frac{217}{8} = 27 frac{1}{8}$

$7 frac{3}{20} + 14 frac{8}{10} = 7 frac{3}{20} + 14 frac{4 div 2}{5 div 2} = frac{143}{20} + frac{74}{5} = frac{143 + 4 times 74}{20} = frac{439}{20} = 21 frac{19}{20}$
