a)
[tex] \frac{2}{6} = \frac{1}{3} [/tex]
[tex] \frac{5}{15} = \frac{1}{3} [/tex]
b) [tex] \frac{12}{18} = \frac{2}{3} [/tex]
[tex] \frac{6}{10} = \frac{3}{5} [/tex]
c)
[tex] \frac{4}{20} = \frac{1}{5} [/tex]
[tex] \frac{14}{30} = \frac{7}{15} [/tex]
d)
[tex] \frac{15}{55} = \frac{3}{11} [/tex]
[tex] \frac{28}{35} = \frac{4}{5} [/tex]
10.
[tex] \frac{6}{12} = \frac{3}{6} = \frac{1}{2} [/tex]
[tex] \frac{24}{60} = \frac{12}{30} = \frac{6}{15} = \frac{2}{5} [/tex]
[tex] \frac{50}{75} = \frac{10}{15} = \frac{2}{3} [/tex]
[tex] \frac{12}{60} = \frac{6}{30} = \frac{2}{10} = \frac{1}{5} [/tex]
[tex] \frac{15}{80} = \frac{3}{16} [/tex]
Mam nadzieję, że pomogłam.
