Zad. 9
a) [tex]\frac{2}{7} + \frac{4}{7} = \frac{6}{7}[/tex]
b) [tex]\frac{6}{8} + \frac{7}{8} = 1\frac{5}{8}[/tex]
c) [tex]2\frac{4}{9} + \frac{3}{9} = 2\frac{7}{9}[/tex]
d) [tex]3\frac{7}{8} + 2\frac{3}{9} = 5\frac{10}{8} = 6\frac{1}{4} \\[/tex]
e) [tex]\frac{15}{17} - \frac{8} {17} = \frac{7}{17}[/tex]
f) [tex]5\frac{18}{23}- 3\frac{11}{23} = 2\frac{7}{23}[/tex]
g) [tex]7- \frac{5}{9} = 6\frac{4}{9}[/tex]
h) [tex]4 \frac{3}{8} - 2\frac{7}{8} =1\frac{4}{8} = 1\frac{1}{2}[/tex]
