a)
[tex] \frac{1}{6} \times \frac{1}{2} = \frac{1}{12} [/tex]
b)
[tex] \frac{1}{2} \times 1 \frac{1}{3} = \frac{1}{2} \times \frac{4}{3} = \frac{1}{1} \times \frac{2}{3} = \frac{2}{3} [/tex]
c)
[tex] \frac{2}{3} \times \frac{4}{6} = \frac{1}{3} \times \frac{4}{3} = \frac{4}{9} [/tex]
d)
[tex] \frac{1}{5} \times \frac{5}{7} = \frac{1}{1} \times \frac{1}{7} = \frac{1}{7} [/tex]
Myślę że pomogłem ;)
