Question

mn giúp mình bài này vs nha

Answer 1

`1+2:(2/3-1/6).(-2,25)`

`=1+2:1/2.(-2,25)`

`=1+4.(-2,25)`

`=1-9=-8`

Answer 2

\(g,=1+2:\left(\dfrac{2.2-1}{6}\right).\left(-2,25\right)\\ =1+2:\dfrac{1}{2}.\left(-2,25\right)\\ =1+4.\left(-2,25\right)\\ =1+-9\\ =-8\)

Answer 3

Answer 4

= \(1+2:\left(\dfrac{4}{6}-\dfrac{1}{6}\right)\cdot\left(-2.25\right)\) =\(1+2\cdot\dfrac{6}{5}\cdot\dfrac{9}{4}\) =\(1+\dfrac{27}{5}\) =\(\dfrac{32}{5}\)
