7 over 18
Unfortunately, 2 over 2 minus 1 equals 5 over 6 is just a wrong answer! If it is 2 over 2, minus 1, the answer is that it equals zero. If it is 2, over 2 minus 1, the answer is that it equals 2.
It is: 2/7 minus 5/8 is = -19/56
7/11 minus 2/5 is 13/55
3 minus 3/18 is 2 5/6
7/18 - 5/18 = 2/18 = 1/9
4/-9 − 5/2 = -53/18 or -217/18
17/18 - 2/3 = 17/18 - 12/18 = 5/18
5 over 18
1/2 − 5/9 = -1/18
18/20 - 5/20 = 13/20
40/55 - 22/55 = 18/55
-7/9 - 5/10 = -7/9 - 1/2 = -14/18 - 9/18 = -23/18
2 minus 2/5 plus 1/2 minus 4 = -1.9
2 minus 5/2 equals -1/2
