4 2/9 + 3 4/9 - 6 5/9=7 6/9-6 5/9=1 1/9
3 - 2 3/11 + 2 5/11 =2 11/11-2 3/11+2 5/11=3 2/11
(8 1/8 - 5 7/8 ) + 2 5/8=(7 9/8-5 7/8)+ 2 5/8=2 2/8+ 2 5/8=4 7/8
( 9 1/5 - 3) - 2 4/5=6 1/5-2 4/5=5 6/5-2 4/5=3 2/5
3 3/8 + (1 2/8 - 3/8)=3 3/8 + (10/8-3/8)=3 3/8 + 7/8=4 2/8=4 1/4
(5 3/7 + 2 1/7) - 4 5/7=7 4/7-4 5/7=6 11/7-4 5/7=2 6/7
