( 1 + (-8) - ( 2 - (-1) ) * ( -7/2 ) / ( -1/4 - (-1) )
I'm guessing that you meant to put another parenthesees here..
( 1 + (-8) - ( 2 - (-1) ) ) * ( -7/2 ) / ( -1/4 - (-1) )
= ( 1 - 8 - ( 2 + 1 ) ) * ( -7/2 ) / ( -1/4 + 1 )
= ( 1 - 8 - 3 ) * ( -7/2 ) / ( 3/4 )
= ( -10 ) * ( -7/2 ) * ( 4/3 )
= 140 / 3
