( -8/9 + 7/5 - 2/11 ) - ( -2/5 - 17/9 -13/11 )

Answer 1

(-8/9 + 7/5 - 2/11) - (-2/5 - 17/9 - 13/11)

= -8/9 + 7/5 - 2/11 + 2/5 + 17/9 + 13/11

= (-8/9 + 17/9) + (7/5 + 2/5) + (-2/11 + 13/11)

= 1 + 9/5 + 1

= 19/5

Answer 2

(-8/9 +7/5 - 2/11) - (-2/5-17/9-13/11)

=-8/9 +7/5 - 2/11 +2/5 +17/9 +13/11

=(-8/9 + 17/9) +(7/5+2/5) (-2/11+13/11)

=11/9 + 9/5 + 1

= 55/45 + 81/45 +45/45
