Odpowiedź:
a) [tex]4\frac{3}{7} +1\frac{1}{5}=4\frac{15}{35}+1\frac{7}{35}=5\frac{22}{35} \\[/tex]
b) [tex]5\frac{2}{3} -2\frac{1}{4}=5\frac{8}{12}-2\frac{3}{12}=3\frac{5}{12}[/tex]
c) [tex]4\frac{3}{10} -2\frac{1}{5}=4\frac{3}{10} -2\frac{2}{10}=2\frac{1}{10}[/tex]
d) [tex]3\frac{2}{9} +1\frac{5}{6}=3\frac{4}{18} +1\frac{15}{18}=4\frac{19}{18}=5\frac{1}{18}[/tex]
e) [tex]7\frac{3}{4} -5\frac{1}{3}=7\frac{9}{12} -5\frac{4}{12}=2\frac{5}{12}[/tex]
f) [tex]4\frac{2}{15} +2\frac{7}{10} =4\frac{4}{30}+2\frac{21}{30} =6\frac{25}{30}[/tex]
g) [tex]11\frac{1}{11} +3\frac{2}{33} =11\frac{3}{33} +3\frac{2}{33} =14\frac{5}{33}[/tex]
h) [tex]4\frac{5}{7} -1\frac{1}{2} =4\frac{10}{14} -1\frac{7}{14} =3\frac{3}{14}[/tex]
i) [tex]2\frac{3}{7} -\frac{2}{5} =2\frac{15}{35} -\frac{14}{35} =2\frac{1}{35}[/tex]
