Помогите с 4 примером

Answer 1

$\tt\displaystyle 4)~\Big(-\frac{7}{18}+\frac{11}{12}\Big):\Big(-\frac{19}{48}\Big)=\\\\\\=\frac{-14+33}{36}\cdot\Big(-\frac{48}{19}\Big)=\frac{19}{36} \cdot\Big( -\frac{48}{19}\Big)=-\frac{48}{36}=\\\\\\=-\frac{4}{3}=-1\frac{1}{3}$

Answer 2

Объяснение:

4)

$( - \frac{7}{18} + \frac{11}{12} ) \div ( - \frac{19}{48} ) =$

$- \frac{7}{18} + \frac{11}{12} = \frac{19}{36}$

$\frac{19}{36} \div ( - \frac{19}{48} ) = - 1 \frac{1}{3}$

$- 1 \frac{1}{3} = - \frac{4}{3}$
