Answer 1

$\frac{5}{6} : \frac{3}{2} = \frac{5}{6} \cdot \frac{2}{3} = \frac{10}{18} = \frac{5}{9}$

$\frac{4}{7} : \frac{3}{7} = \frac{4}{7} \cdot \frac{7}{3} = \frac{28}{21} = \frac{4}{3}$

$\frac{6}{9} : \frac{5}{3} = \frac{6}{9} \cdot \frac{3}{5} = \frac{18}{45} = \frac{2}{5}$

$\frac{5}{12} : \frac{15}{8} = \frac{5}{12} \cdot \frac{8}{15} = \frac{40}{180} = \frac{2}{9}$

$\frac{9}{8} : \frac{3}{4} = \frac{9}{8} \cdot \frac{4}{3} = \frac{36}{24} = \frac{3}{2}$

$\frac{5}{6} : \frac{10}{9} = \frac{5}{6} \cdot \frac{9}{10} = \frac{45}{60} = \frac{3}{4}$

Sper că te-am ajutat!
