6.
a)
[tex] \frac{5}{6} + \frac{1}{6} = 1[/tex]
[tex] \frac{5}{6} + \frac{25}{6} = 5[/tex]
b)
[tex] \frac{8}{9} + \frac{1}{9} = 1[/tex]
[tex] \frac{8}{9} + \frac{28}{9} = 4[/tex]
c)
[tex] \frac{5}{12} + \frac{7}{12} = 1[/tex]
[tex] \frac{5}{12} + \frac{79}{12} = 7[/tex]
7.
a)
[tex]1 - \frac{7}{8} = \frac{1}{8} [/tex]
b)
[tex]1 - \frac{5}{7} = \frac{2}{7} [/tex]
c)
[tex]2 - \frac{6}{7} = 1 \frac{1}{7} [/tex]
d)
[tex]2 - \frac{3}{5} = 1 \frac{2}{5} [/tex]
e)
[tex]3 - \frac{5}{19} = 2 \frac{14}{19} [/tex]
f)
[tex]3 - \frac{2}{11} = 2 \frac{9}{11} [/tex]
Myślę że pomogłem ;)
