ajuți mă va rog frumos vă rog​

Answer 1

$a) = \frac{11}{4} + 1 \frac{5}{6} - \frac{29}{8} - \frac{67}{12}$

$= \frac{11}{4} + \frac{11}{6} - \frac{29}{8} - \frac{67}{12}$

$= - \frac{37}{8}$

$d) = \frac{5}{4} + (( \frac{73}{36} - \frac{19}{18} ) - ( \frac{29}{9} - \frac{7}{3} ))$

$= \frac{5}{4} + ( \frac{35}{36} - \frac{7}{9} )$

$= \frac{5}{4} + \frac{7}{36}$

$= \frac{13}{9}$
