[tex]7 \frac{1}{5} \div 1 \frac{1}{5} = \frac{36}{5} \times \frac{5}{6} = \frac{180}{30} = 6[/tex]
[tex]2 \frac{3}{4} \div 4 \frac{2}{5} = \frac{11}{4} \times \frac{5}{22} = \frac{55}{88} [/tex]
[tex]1 \frac{5}{12} \div 1 \frac{7}{10} = \frac{17}{12} \times \frac{10}{17} = \frac{170}{204} [/tex]
mam nadzieję że jest dobrze
