Первое действие:

$\dfrac{3}{19} - 1 = \dfrac{-16}{19}$

Второе действие:

$5\dfrac{10}{19}:\dfrac{-16}{19}=\dfrac{5\cdot19+10}{19}:\dfrac{-16}{19}=\dfrac{105}{19}:\dfrac{-16}{19}=-\dfrac{105}{19}:\dfrac{19}{16}=-\dfrac{105}{16}=-6\dfrac{9}{16}$

Третье действие:

$2\cdot1\dfrac{1}{2}=2\cdot1 + 2\cdot\dfrac{1}{2} = 2 + 1 = 3$

Ответ:

$-6\dfrac{9}{16}-3=-9\dfrac{9}{16}$
