a)
[tex] \frac{3}{4} \times \frac{1}{5} = \frac{3}{20} [/tex]
b)
[tex] \frac{6}{8} \times \frac{1}{4} = \frac{6}{32} = \frac{3}{16} [/tex]
c)
[tex] \frac{5}{8} \times 1 \frac{1}{3} = \frac{5}{8} \times \frac{4}{3} = \frac{5}{2} \times \frac{1}{3} = \frac{5}{6} [/tex]
d)
[tex] \frac{4}{12} \times 3 \frac{1}{2} = \frac{4}{12} \times \frac{7}{2} = \frac{2}{12} \times \frac{7}{1} = \frac{14}{12} = 1 \frac{2}{12} = 1 \frac{1}{6} [/tex]
Myślę że pomogłem ;)
