[tex]\frac{3}{5}:2=\frac{3}{5}\cdot\frac{1}{2}=\frac{3\cdot1}{5\cdot2}=\frac{3}{10}\\\\\frac{5}{9}:3=\frac{5}{9}\cdot\frac{1}{3}=\frac{5\cdot1}{9\cdot3}=\frac{5}{27}\\\\\frac{7}{9}:3=\frac{7}{9}\cdot\frac{1}{3}=\frac{7\cdot1}{9\cdot3}=\frac{7}{27}\\\\\frac{4}{11}:5=\frac{4}{11}\cdot\frac{1}{5}=\frac{4\cdot1}{11\cdot5}=\frac{4}{55}[/tex]
Odpowiedź:
3/5 : 2 = 3/5 * 1/2 = 3/10
5/9 : 3 = 5/9 * 1/3 = 5/27
7/9 : 3 = 7/9 * 1/3 = 7/27
4/11 : 5 = 4/11 * 1/5 = 4/55
