Giúp mik vs 

Answer 1

`B=-3-2/3+3/5(-10/9-25/3)-5/6`

`=-3-2/3-5/6+3/5(-10/9-50/9)`

`=-3-4/6-5/6+3/5*(-60)/9`

`=-3-9/6-4`

`=-7-3/2=-17/2`

Answer 2

Lời giải:
\(B=-3-\frac{2}{3}+\frac{3}{5}(\frac{-10}{9}-\frac{25}{3})-\frac{5}{6}\)

\(=-3-(\frac{2}{3}+\frac{5}{6})+\frac{3}{5}.(\frac{-10}{9}-\frac{75}{9})\)

\(=-3-\frac{4+5}{6}+\frac{3}{5}.\frac{-85}{9}=-3-\frac{9}{6}-\frac{17}{3}=-(3+\frac{9}{6}+\frac{34}{6})=\frac{-61}{6}\)
