12 is as it has 6 factors and is the smallest and first to have. Factors of 12= 1, 2, 3, 4, 6, and 12
1/6 + 1/12 = 2/12 + 1/12 = 3/12 = 1/41/6 = 2/12 + 1/12 = 3/12 = 1/4
12
Obviously there are 12 fractions that comprise the list of "twelvths" Starting from lowest to highest: 1/12, 2/12 or 1/6, 3/12 or 1/4, 4/12 or 1/3, 5/12, 6/12 or 1/2, 7/12, 8/12 or 2/3, 9/12 or 3/4, 10/12 or 5/6, 11/12, and 12/12 or 1/1. Simplified list below: 1/12 1/6 1/4 1/3 1/2 7/12 2/3 3/4 5/6 11/12 1/1
12 minus 11 1/6 is 5/6
-1/6 + 1/12 = -2/12 + 1/12 = -1/12-1/6 + 1/12 = -2/12 + 1/12 = -1/12-1/6 + 1/12 = -2/12 + 1/12 = -1/12-1/6 + 1/12 = -2/12 + 1/12 = -1/12
12 is the LCM of any of the following 44 sets:{12},{1, 12}, {2, 12}, {3, 4}, {3, 12}, {4, 6} , {4, 12}, {6, 12},{1, 2, 12}, {1, 3, 4}, {1, 3, 12}, {1, 4, 6}, {1, 4, 12},{1, 6, 12}, {2, 3, 4}, {2, 3, 12}, {2, 4, 6}, {2, 4, 12},{2, 6, 12}, {3, 4, 6}, {3, 4, 12}, {3, 6, 12}, {4, 6, 12},{1, 2, 3, 12}, {1, 2, 4, 12}, {1, 2, 6, 12}, {1, 3, 4, 12},{1, 3, 6, 12}, {1, 4, 6, 12}, {1, 2, 4, 6}, {1, 3, 4, 6},{1, 2, 3, 4}, {2, 3, 4, 6}, {2, 3, 4, 12}, {2, 3, 6, 12},{2, 4, 6, 12}, {3, 4, 6, 12},{1, 2, 3, 4, 6}, {1, 2, 3, 4, 12}, {1, 2, 3, 6, 12},{1, 2, 4, 6, 12}, {1, 3, 4, 6, 12}, {2, 3, 4, 6, 12},{1, 2, 3, 4, 6, 12}.
1/12 + 6/12 = 7/121/12 + 6/12 = 7/12
6:12 = 1/26:12 = 1/26:12 = 1/26:12 = 1/2
(1/6) /(1/12) = 12/6 = 2
(6/12) - (1/3) = (6/12) - (4/12) = 2/12 = 1/6
1/6 + 12 = 12 1/6 or 12.1666...
12/72 = (1×12)/(6×12) = 1/6 = 0.1666... ≈ 0.167
no 6/12 is 6 times larger than 1/12 though 6/12 is equal to 1/2
7/12+1/12+1/6=1o/12
2/12 = 1/6 times.2/12 = 1/6 times.2/12 = 1/6 times.2/12 = 1/6 times.
