a)
[tex] \frac{1}{8} \times \frac{7}{2} = \frac{7}{16} [/tex]
b)
[tex] \frac{4}{7} \times \frac{3}{8} = \frac{1}{7} \times \frac{3}{2} = \frac{3}{14} [/tex]
c)
[tex] \frac{6}{7} \times \frac{21}{16} = \frac{3}{1} \times \frac{3}{8} = \frac{9}{8} = 1 \frac{1}{8} [/tex]
d)
[tex]2 \frac{6}{7} \times 1 \frac{1}{10} = \frac{20}{7} \times \frac{11}{10} = \frac{2}{7} \times \frac{11}{1} = \frac{22}{7} = 3 \frac{1}{7} [/tex]
Myślę że pomogłem ;)
