11/7 : ( 23/7 - 41/2 ) + ( - 1 ) = 11/7 : ( 46/14 - 287/14 ) + ( - 1 ) = 11/7 : [ ( 46 - 287 ) / 14 ] + ( - 1 ) = 11/7 : [ - 241/14 ] + ( - 1 ) = 11/7 × [ - 14/241 ] + ( - 1 ) = - ( 14/241 × 11/7 ) + ( - 1 ) = - ( 14 × 11 ) / ( 241 × 7 ) + ( - 1 ) = - 154/1687 + ( - 1 ) = - 154/1687 - 1 = - 1 - 154/1687 = - 1 154/1687.
