Answer 1

$\frac{7}{8} - \frac{1}{8} = \frac{6}{8} rosu$
$\frac{9}{10} - \frac{1}{10} = \frac{8}{10} rosu$
$\frac{2}{4} - \frac{1}{4} = \frac{1}{4} rosu$
$\frac{8}{9} - \frac{2}{9} = \frac{6}{9} rosu$
$\frac{3}{5} - \frac{1}{5} = \frac{2}{5} rosu$
$\frac{7}{12} - \frac{1}{12} = \frac{6}{12} rosu$
$\frac{7}{11} - \frac{5}{11} = \frac{2}{11} rosu$
$\frac{7}{8} - \frac{2}{8} = \frac{5}{8} rosu$
