Cześć :)
[tex]2 * 2\frac{3}4} = 2*\frac{11}{4} = \frac{22}{4} = 5\frac{2}{4} = 5\frac{1}{2}[/tex]
[tex]4 *2 \frac{1}{4} = 4* \frac{9}{4} = \frac{36}{4} = 9[/tex]
[tex]4 * 2\frac{3}{4} = 4* \frac{11}{4} = \frac{44}{4} = 11[/tex]
[tex]4 * 1\frac{1}{7} = 4 * \frac{8}{7} = \frac{32}{7} = 4 \frac{4}{7}[/tex]
Pozdrawiam!
