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.
2 minus 5/2 equals -1/2
2/5 minus 4/9 equals -2/45
5 over 6 minus 2 in simplest form equals -1 1/6
16/21 minus two equals -1 5/21
x=3/2
-5, 5
x = 2 :D
-2
3 - 5 = -2
2/5 + 3/4 - 1/2 equals 8/20 + 15/20 - 10/20 which adds up to 8/20 This equals 4/5
6/11 minus 5/6 equals -19/66
