a)
[tex] \frac{2}{4} - \frac{1}{4} = \frac{1}{4} [/tex]
b)
[tex] \frac{7}{9} - \frac{2}{9} = \frac{5}{9} [/tex]
c)
[tex]3 - \frac{2}{5} = 2 \frac{3}{5} [/tex]
d)
[tex]2 \frac{2}{7} - 1 = 1 \frac{2}{7} [/tex]
e)
[tex] \frac{5}{11} - \frac{5}{11} = 0[/tex]
f)
[tex] \frac{11}{32} - 0 = \frac{11}{32} [/tex]
Myślę że pomogłem ;)
