`{-5}/9 . 2/3 + {-5}/9 . 11/3 - 5/9`
`= -5/9 . 2/3 - 5/9 . 11/3 - 5/9 . 1`
`= -5/9 . (2/3 + 11/3 + 1)`
`= -5/9 . (13/3 + 1)`
`= -5/9 . 16/3`

`(-5)/9 . 2/3 + (-5)/9) . 11/3 - 5/9`
= `(-5)/9 . 2/3 + (-5/9) . 11/3 + (-5)/9 . 1`
= `(-5)/9 . ( 2/3 + 11/3 + 1 )`
=`(-5)/9 . (2/3 + 11/3 + 3/3)`
=`(-5)/9 . 16/3`
=`{-5 . 16}/ {9 . 3}`
=`-80/27`
