Answer 1

`25% - 1``1/2` `- (-1/2)^2 + 0,25 : 1/12`

`= 1/4 - 3/2 - 1/4 + 1/4 : 1/12`

`= -5/4 - 1/4 + 3`

`= -3/2 + 3`

`= -3/2 + 6/2`

`= 3/2`

Answer 2

\(25\%-1\dfrac{1}{2}-\left(-\dfrac{1}{2}\right)^2+0,25:\dfrac{1}{12}\)

\(=\dfrac{1}{4}-\dfrac{3}{2}-\dfrac{1}{4}+\dfrac{1}{4}\cdot12\)

\(=\dfrac{1}{4}-\dfrac{3}{2}-\dfrac{1}{4}+3\)

\(=\dfrac{1}{4}+\left(\dfrac{3}{2}-\dfrac{1}{4}\right)\)

\(=\dfrac{1}{4}+\dfrac{5}{4}\)

\(=\dfrac{6}{4}\)

\(=\dfrac{3}{2}\)

Answer 3

Nếu mình làm đúng thì tick mình nhé!

Answer 4

`25% - 1 1/2 - (-1/2)^2 + 0,25 : 1/12`

`=> 1/4 - 3/2 + 1/4 + 1/4 xx 12`

`=> -5/4 + 1/4 + 3`

`=> -1 + 3`

`=> 2`
