Jawaban:

$1. frac{3}{5}+frac{2}{3}=frac{9+10}{15}=frac{19}{15}=1 frac{4}{15}$

$2. frac{4}{5}-frac{3}{8}=frac{32 - 15}{40}=frac{17}{40}$

$3. 4frac{2}{7}+3frac{1}{2}=7 frac{2+7}{14}=7frac{9}{14}$

$4. 3frac{2}{3}+1frac{5}{9}=4 frac{6+5}{9}=4frac{11}{9}=5 frac{2}{9}$

$5. 3 - (2frac{5}{6}+1frac{7}{4})=3 - (2 frac{10}{12}+1frac{21}{12})$

$=3-(3frac{31}{12})=3-(5frac{7}{12})=-2frac{7}{12}$
