Question

(1,37).2/9-7,37.(-2/9)

Answer 1

\(1,37.\dfrac{2}{9}-7,37.\left(-\dfrac{2}{9}\right)=1,37.\dfrac{2}{9}-\left(-7,37\right).\dfrac{2}{9}=\left[1,37-\left(-7,37\right)\right].\dfrac{2}{9}=8,74.\dfrac{2}{9}=\dfrac{437}{225}\)

Answer 2

`1,37``.``2/9-7,37``.``(-2/9)`

`=` `1,37``.``2/9-(-7,37)``.``2/9`

`=` `1,37``.``2/9+7,37``.``2/9`

`=` `(1,37+7,37)``.``2/9`

`=` `8,74``.``2/9`

`=` `437/225`
