Zad 2
a) [tex]\frac{7}{9}+\frac{4}{9}=\frac{11}{9}=1\frac{2}{9}[/tex]
b) [tex]\frac{5}{7}+\frac{6}{7} =\frac{11}{7}=1\frac{4}{7}[/tex]
c) [tex]2\frac{2}{5}+\frac{4}{5}=2\frac{6}{5}=3\frac{1}{5}[/tex]
Zad. 3
a) [tex]\frac{2}{3}+\frac{1}{4}=\frac{8}{12}+\frac{3}{12}=\frac{11}{12}[/tex]
b) [tex]\frac{5}{9}+\frac{3}{5}=\frac{25}{45}+\frac{27}{45}=\frac{52}{45}=1\frac{7}{45}[/tex]
c) [tex]\frac{2}{3}+\frac{4}{5}=\frac{10}{15}+\frac{12}{15}=\frac{22}{15}=1\frac{7}{15}[/tex]
d) [tex]\frac{5}{8}+\frac{3}{7}=\frac{35}{56} +\frac{24}{56}=\frac{59}{56}=1\frac{3}{56}[/tex]
e) [tex]1\frac{1}{2}+2\frac{3}{8}=1\frac{4}{8}+2\frac{3}{8}=3\frac{7}{8}[/tex]
f) [tex]\frac{2}{9}+1\frac{7}{27}=\frac{6}{27}+1\frac{7}{27}=1\frac{13}{27}[/tex]
g) [tex]1\frac{5}{6}+3\frac{1}{9}=1\frac{15}{18}+3\frac{2}{18}=4\frac{17}{18}[/tex]
h) [tex]2\frac{1}{10}+1\frac{7}{15}=2\frac{3}{30}+1\frac{14}{30}=3\frac{17}{30}[/tex]
