$\bf 1\dfrac{8}{9} -\dfrac{5}{6}+2\dfrac{3}{4}=$

$\bf \dfrac{1\cdot9+8}{9} -\dfrac{5}{6}+\dfrac{2\cdot4+3}{4}=$

$\bf \dfrac{17}{9} -\dfrac{5}{6}+\dfrac{11}{4}=$

$\bf \dfrac{4\cdot17}{36} -\dfrac{5\cdot6}{36}+\dfrac{11\cdot9}{36}=$

$\bf \dfrac{68}{36} -\dfrac{30}{36}+\dfrac{99}{36} =$

$\boxed{\bf \dfrac{137}{36} }$
