Szczegółowe wyjaśnienie:
[tex]1 \frac{8}{10} \times \frac{5}{6} = \frac{18}{10} \times \frac{5}{6} = \frac{3}{2} \times 1 = 1 \frac{1}{2} [/tex]
[tex]1 \frac{1}{2} \times \frac{1}{2} = \frac{3}{2} \times \frac{1}{2} = \frac{3}{4} [/tex]
[tex]2 \frac{2}{4} \times \frac{4}{9} = \frac{10}{4} \times \frac{4}{9} = \frac{10}{9} = 1 \frac{1}{9} [/tex]
[tex]1 \frac{2}{4} \times \frac{4}{8} = \frac{6}{4} \times \frac{4}{8} = \frac{3}{1} \times \frac{1}{4} = \frac{3}{4} [/tex]
[tex]1 \frac{1}{8} \times 1 \frac{2}{3} = \frac{9}{8} \times \frac{5}{3} = \frac{3}{8} \times \frac{5}{1} = \frac{15}{8} = 1 \frac{7}{8} [/tex]

[tex]3 \frac{9}{12} \times \frac{2}{5} = \frac{45}{12} \times \frac{2}{5} = \frac{9}{6} \times \frac{1}{1} = 1 \frac{3}{6} = 1 \frac{1}{2} [/tex]
[tex] \frac{5}{18} \times 4 \frac{1}{2} = \frac{5}{18} \times \frac{9}{2} = \frac{5}{2} \times \frac{1}{2} = \frac{5}{4} = 1 \frac{1}{4} [/tex]
[tex] \frac{3}{4} \times 2 \frac{3}{6} = \frac{3}{4} \times \frac{15}{6} = \frac{1}{4} \times \frac{15}{2} = \frac{15}{8} = 1 \frac{7}{8} [/tex]
[tex] \frac{1}{3} \times 3 \frac{3}{4} = \frac{1}{3} \times \frac{15}{4} = 1 \times \frac{5}{4} = 1 \frac{1}{4} [/tex]
[tex] \frac{2}{3} \times 1\frac{8}{12} = \frac{2}{3} \times \frac{20}{12} = \frac{40}{36} = \frac{10}{9} = 1 \frac{1}{9} [/tex]
