6 19 - 4 89=?
8 37 - 4 47=?
(1 18 + 8 58) - 3 28=
4 811 - (5 211 - 3 711)=
16 1011 -( 1 411 + 7 911)=

6 1/9 - 4 8/9 = 55/9 - 44/9 = 11/9 = 1 2/9
8 3/7 - 4 4/7 = 59/7 - 32/7 = 27/7 = 3 6/7
(1 1/8 + 8 5/8) - 3 2/8 = 9 6/8 - 3 2/8 = 6 4/8 = 6 1/2
4 8/11 - (5 2/11 - 3 7/11) = 4 8/11 - (57/11 - 40/11) = 4 8/11 - 17/11 = 4 8/11 - 1 6/11 = 3 2/11
16 10/11 - (1 4/11 + 7 9/11) = 16 10/11 - 9 2/11 = 7 8/11

6 19 - 4 89=55/9-44/9=11/9=1 2/9. 8 37 - 4 47=59/7-32/7=27/7=3 6/7. (1 18 + 8 58) - 3 28=9/8+69/8-26/8=52/8=6 4/8=6 1/2. 4 811 - (5 211 - 3 711)=52/11-(57/11-40/11)=52/11-17/11=35/11=3 2/11 . 16 1011 -( 1 411 + 7 911)=186/11-(15/11+86/11)=186/11-101/11= 85/11= 7 8/11.
