$\displaystyle 1)-3\frac{1}{4}-(-5\frac{2}{9})=-\frac{13}{4}+5\frac{2}{9}=-\frac{13}{4}+\frac{47}{9}=\frac{71}{36}=1\frac{35}{36}\\ \\2)\frac{8}{9}+(-3\frac{1}{4})=\frac{8}{9}-3\frac{1}{4}=\frac{8}{9}-\frac{13}{4}=-\frac{85}{36}=-2\frac{13}{36}\\ \\3)-5\frac{1}{3}:(-5\frac{2}{9})=\frac{16}{3}*\frac{9}{47}=16*\frac{3}{47}=\frac{48}{47}=1\frac{1}{47}\\ \\4)-3\frac{1}{6}+2\frac{1}{4}:(-5\frac{1}{6})-12=-\frac{19}{6}-\frac{27}{62}-12=-\frac{1451}{93}=-15\frac{56}{93}$
