Question

(-13 .2/5 + -2/9 : 5/2 + 2/5 . 11/9) . 5/2

 

Answer 1

`(-13 .2/5 +( -2/9) : 5/2 + 2/5 . 11/9) . 5/2`

`=(-13 . 2/5 - 2/9 . 2/5 + 2/5 . 11/9).5/2`

`=[ 2/5 . ( -13 - 2/9 + 11/9).5/2`

`=[2/5. (-12)] . 5/2`

`=(-24)/5 . 5/2`

`= (-24.5)/(5.2)`

`=-120/10`

`=-12`

 

Answer 2

\(\left(-13.\dfrac{2}{5}+-\dfrac{2}{9}:\dfrac{5}{2}+\dfrac{2}{5}.\dfrac{11}{9}\right).\dfrac{5}{2}\)

\(=\left[\dfrac{2}{5}\left(-13-\dfrac{2}{9}+\dfrac{11}{9}\right)\right]\dfrac{5}{2}\)

\(=\dfrac{2}{5}.-12.\dfrac{5}{2}=-12\)

`(-13 . 2/5 + -2/9 : 5/2 + 2/5 . 11/9) . 5/2`

`= (-13 . 2/5  + -2/9 . 2/5 + 2/5 . 11/9) . 5/2`

`= [(-13 + -2/9 + 11/9) . 2/5) . 5/2`

`= (-12) . 2/5 . 5/2`

`= -12 . 1`

`= -12`
