`c)`

`32/5 - ( -9/8 + 12/5 ) + (( -1 )/2 )^3`

`= 32/5 + 9/8 - 12/5 + ( -1 )/8`

`= ( 9/8 + ( -1 )/8 ) + ( 32/5 - 12/5 )`

`= 8/8 + 20/5`

`= 1 + 4`

`= 5`

`d)`

`15/17 - 3 . ( 10/3 + 5/17 ) + ( -1 )^2022`

`= 15/17 - 3 . 10/3 - 3 . 5/17 + 1`

`= 15/17 - 10 - 15/17 + 1`

`= ( 15/17 - 15/17 ) + ( 1 - 10 )`

`= 0 + ( -9 )`

`= -9`
