$\frac{5}{6}+ 0,25= \frac{5}{6}+ \frac{1}{4} = \frac{10+3}{12} = \frac{13}{12}$
$4 \frac{1}{3}: \frac{13}{12}= \frac{13}{3}* \frac{12}{13}=4$
$\frac{7}{12} - \frac{2}{15}= \frac{35-8}{60}= \frac{27}{60}= \frac{9}{20}$
$\frac{9}{20}:0,9= \frac{9}{20}: \frac{9}{10}= \frac{9}{20}* \frac{10}{9}= \frac{1}{2}=0,5$
4:0,5=8
$\frac{7}{12}+ \frac{1}{9}= \frac{21+4}{36}= \frac{25}{36}$
$3 \frac{6}{10}* \frac{25}{36}= \frac{36}{10}* \frac{25}{36}= \frac{5}{2}$
$\frac{5}{2}=2,5$
$\frac{5}{8}- \frac{1}{3}= \frac{15-8}{24}= \frac{7}{24}$
$\frac{7}{24}*1 \frac{5}{7}= \frac{7}{24}* \frac{12}{7}= \frac{1}{2}=0,5$
2,5:0,5=5
8-5=3
