13,3 + 2 – 12 : 1 1/2 =…

$frac{133}{10} + 2 - (12 *frac{2}{11})\frac{133}{10} + 2 - frac{24}{11} \frac{1463 + 220 - 240}{110} = frac{1443}{110}$

$25 + frac{3}{2} - (2 * frac{7}{15} * 3)\25 + frac{3}{2} - frac{14}{5} \frac{250 + 15 - 28}{10} = frac{237}{10} = 23,7$

$frac{29}{30} + (frac{2}{5} * frac{7}{9}) \frac{29}{30} + frac{14}{45}\frac{87 + 28}{90} = frac{115}{90} = frac{23}{18}$
