(11/18) - (1/6) = (11/18) - (3/18) = (11-3)/18 = 8/18 = 4/9
1 − 11/29 = 18/29
11/6 − 7/9 = 7/18
1 minus 11/24 is 13/24
11/12 minus 1/16 is 41/48
11/30 - 1/5 - 1/6 = 0
It is -1/11
1 minus 11/21 = 10/21
12 minus 11 1/6 is 5/6
11/12 minus 7/12 is 1/3
19/20 minus 11/12 = 1/30
1 over 18 I think
3/4 minus 1/5 is 11/20
