Explicație pas cu pas:

$\frac{1}{2} :\frac{3}{2} : \frac{5}{3} =(\frac{1}{2} x \frac{2}{3} ) : \frac{5}{3} = \frac{1}{3} :\frac{5}{3} = \frac{1}{3} x \frac{3}{5} = \frac{1}{5}$

$\frac{2}{3} : \frac{4}{9} : \frac{8}{27} =(\frac{2}{3} x \frac{9}{4}) : \frac{8}{27}=\frac{3}{2} : \frac{8}{27} =\frac{3}{2}x\frac{27}{8}  =\frac{81}{16}$

$\frac{5}{3} : \frac{1}{3} : \frac{10}{7} = \frac{5}{3} x \frac{3}{1} : \frac{10}{7} = \frac{5}{1} x \frac{7}{10} = \frac{7}{2}$
