[tex] \frac{2}{4} \times \frac{3}{7} = \frac{2 \times 3}{4 \times 7} = \frac{6}{28} = \frac{3}{14} [/tex]
[tex] \frac{5}{8} \times \frac{1}{2} = \frac{5 \times 1}{8 \times 2} = \frac{5}{16} [/tex]
[tex] \frac{7}{3 } \times \frac{9}{8} = \frac{7 \times 9}{3 \times 8} = \frac{7 \times 3}{1 \times 8} = \frac{21}{8} = 2 \frac{5}{8} [/tex]
[tex] \frac{3}{2} \times \frac{5}{6} = \frac{3 \times 5}{2 \times 6} = \frac{1 \times 5}{2 \times 2} = \frac{5}{4} = 1 \frac{1}{4} [/tex]
[tex]2 \frac{3}{4} \times 5 \frac{1}{3} = \frac{11}{4} \times \frac{16}{3} = \frac{11 \times 16}{4 \times 3} = \frac{11 \times 4}{1 \times 3} = \frac{44}{3} = 14 \frac{2}{3} [/tex]
[tex] \frac{5}{7} \div \frac{3}{7} = \frac{5}{7} \times \frac{7}{3} = \frac{5}{1} \times \frac{1}{3} = \frac{5}{3} = 1 \frac{2}{3} [/tex]
[tex] \frac{8}{5} \div \frac{4}{25} = \frac{8}{5} \times \frac{25}{4} = \frac{2}{1} \times \frac{5}{1} = \frac{10}{1} = 10[/tex]
[tex]4 \frac{1}{4} \div \frac{5}{12} = \frac{17}{4} \times \frac{12}{5} = \frac{17}{1} \times \frac{3}{5} = \frac{51}{5} = 10 \frac{1}{5} [/tex]
[tex] \frac{6}{11} \div 7 \frac{1}{3} = \frac{6}{11} \times \frac{3}{22} = \frac{3}{11} \times \frac{3}{11} = \frac{9}{121} [/tex]
[tex]2 \frac{1}{3} \div 4 \frac{4}{7} = \frac{7}{3} \times \frac{7}{32} = \frac{49}{96} [/tex]
mam nadzieję, że pomogłam :)
