Answer 2

Răspuns:

$\frac{2}{5} - \frac{1}{10} = \frac{4}{10} - \frac{1}{10} = \frac{3}{10}$

$\frac{3}{5} - \frac{3}{7} = \frac{21}{35} - \frac{15}{35} = \frac{6}{35}$

$\frac{5}{9} - \frac{1}{3} = \frac{5}{9} - \frac{3}{9} = \frac{2}{9}$

$\frac{2}{9} - \frac{1}{6} = \frac{4}{18} - \frac{3}{18} = \frac{1}{18}$

$\frac{3}{4} - \frac{5}{8} = \frac{6}{8} - \frac{5}{8} = \frac{1}{8}$

$\frac{5}{12} - \frac{2}{9} = \frac{15}{36} - \frac{8}{36} = \frac{7}{36}$
