18/11 x 5/12 is 15/22
1 + 2 + 3 + 4 + 5 + 6 + 7 + 8 + 9 + 10 + 11 + 12 = 78
1/3 + 1/12 = 5/12
2 over 3 plus 5 over 9 equals 11 over 9 or 1 and 2 ninths.
3/4 + 5/6 = 9/12 + 10/12 = 19/12 = 17/12
11/12 + 11/12 = 22/12 = 1 and 5/6
(5/12) + (11/12) = 16/12 = 4/3Or: 1 and 1/3
5/6 + 1/12 = 11/12
1/2 + 5/12 = 11/12
91 over 60
11 + (-5) + (-12) + (-2) =11 - 5 - 12 - 2 =11 - 19 = -8
3/4 + 5/12 = 56/48 or 7/6 or 11/6
5/8 + 5/12 = 15/24 + 10/24 = 25/24 or 11/24
85/66, which is the same as 1 and 19/66.
The sum of 5/12 and 5/12 is 5/6
