[tex]1) \: 1 \frac{1}{4} \div 2 \frac{1}{5} = \frac{5}{4} \div \frac{11}{5} = \frac{5}{4} \times \frac{5}{11} = \frac{25}{44} [/tex]
[tex]2) \: 5 \frac{1}{2} \div \frac{11}{12} = \frac{11}{2} \times \frac{12}{11} = \frac{1}{1} \times \frac{6}{1} = 6[/tex]
[tex]3) \: 3 \frac{4}{9} \div 1 \frac{1}{5} = \frac{31}{9} \times \frac{5}{6} = \frac{155}{54} = 2 \frac{47}{54} [/tex]
[tex]4) \: \frac{8}{9} \div 1 \frac{3}{9} = \frac{8}{9} \times \frac{9}{12} = \frac{2}{1} \times \frac{1}{3} = \frac{2}{3} [/tex]
[tex]5) \: 4 \frac{1}{3} \div \frac{2}{3} = \frac{13}{3} \times \frac{3}{2} = \frac{13}{1} \times \frac{1}{2} = \frac{13}{2} = 6 \frac{1}{2} [/tex]
[tex]6) \: 6 \frac{1}{7} \div \frac{9}{14} = \frac{43}{7} \times \frac{14}{9} = \frac{43}{1} \times \frac{2}{9} = \frac{86}{9} = 9 \frac{5}{9} [/tex]
Pozdrawiam.
