Zad 4
a) [tex]\frac{6}{12}[/tex]=[tex]\frac{1}{2}[/tex]
b)[tex]1\frac{1}{7}[/tex]
c)[tex]2\frac{2}{9}[/tex]
d) 1
Zad 5
a)
[tex]1 -\frac{3}{14} =\frac{14}{14} - \frac{3}{14} =\frac{11}{14} \\1 -\frac{7}{9} = \frac{9}{9} -\frac{7}{9} =\frac{2}{9}[/tex]
b)
[tex]3-\frac{1}{4} = 2\frac{4}{4} -\frac{1}{4} = 2\frac{3}{4}\\5-\frac{5}{7} = 4\frac{7}{7} -\frac{5}{7} = 4\frac{2}{7}[/tex]
c)
[tex]3\frac{4}{9} -\frac{7}{9} =2\frac{14}{9} -\frac{7}{9} =2\frac{7}{9} \\2\frac{7}{12} -1\frac{11}{12} = 1\frac{19}{12} -1\frac{11}{12} =\frac{8}{12} =\frac{2}3}[/tex]
