Answer 1

Răspuns:

$\frac{m:3}{10} > \frac{m:3:3}{10}$

$m=9,18,27$

$\frac{9:3}{10} >\frac{9:3:3}{10}$

$\frac{3}{10} >\frac{1}{10}$

$m=18$

$\frac{18:3}{10} > \frac{18:3:3}{10}$

$\frac{6}{10} > \frac{2}{10}$

$m=27$

$\frac{27:3}{10} > \frac{27:3:3}{10}$

$\frac{9}{10} > \frac{3}{10}$

$\frac{n}{7} < \frac{n*2}{7} <\frac{n*2+2}{7} <\frac{n*3+3}{7}$

$n=1$

$\frac{1}{7} <\frac{2}{7} < \frac{4}{7} < \frac{6}{7}$
